Favorite quote:

“You can increase your pleasure if you’re willing to do things that don’t feel good at first.”

Let’s get started.

Chapter 1: YOUR INNER MAMMAL (How our brain works)

Our mind cares for your happiness in the same way that it cares for your physical issues.

It is associated with all past experiences, which is why your happiness and your emotions keep fluctuating.

Let’s get to know how chemicals make you happy.

Dopamine, endorphin, oxytocin, and serotonin are four unique brain chemicals that contribute to the emotion we refer to as “happiness.” These “happy chemicals” become active when your brain detects an opportunity for your survival. When something positive comes your way, they will be ready to activate once more because they will then turn off.

Each happy chemical triggers a different good feeling:


When your needs are satisfied, such as when you’re hungry, have eaten, want to play, or do play, dopamine is released.


are produced when you concentrate on the positive aspects of things, which usually helps you to feel the pain caused by them.


This hormone is released when you feel at ease with someone.


This hormone is released after receiving respect from others.

When you are proud of yourself this hormone is released, you can refer to it as pride.


Dopamine: helps in obtaining desired outcomes.

Endorphin: help reduce the pain of an affliction

Oxytocin: helps in building good relationships with people

Serotonin: increases social security.

You now understand how happy chemicals do function.

Happy chemical control comes from a small structure in the brain, which are the same in everyone.

The hippocampus, amygdala, pituitary, hypothalamus, and other parts of the brain are called the limbic system.

the limbic system releases neurochemicals to signal the body,

When something is good for you, move toward it, and if something is bad for you, stay away from it,

Let’s now examine each happy chemical individually.


Dopamine explains what you need, demonstrates how to get it, and makes you feel the pleasure you will experience if you do.

Because of dopamine, when a lion sees his hunter, he feels compelled to hunt him and begins to feel happy before hunting.

A sportsperson experiences great happiness when he wins, but he has already experienced it.

He moves forward because of the feeling, and he experiences the same feeling when he succeeds.

Because of how he feels, he is only driven to continue.

Dopamine is to blame because it makes you happy and helps you meet your needs.

Meet your Endorphin

When you get hurt, the endorphin hormone helps you for that time so that you can survive.

It doesn’t make you away from pain, it just makes you get rid of that pain in the time of emergency so that you can survive.

You must have noticed that when you get hurt, it doesn’t hurt that much.

But after some time too much pain starts, it is due to endorphins.

Meet your Oxytocin

When you trust someone or when someone trusts you, oxytocin is released, which makes you feel good.

The oxytocin hormone is released when you feel completely confident in someone because you like their behavior.

Meet Your Serotonin

When you feel respected, serotonin is released; this serotonin hormone inspires you to carry out more deeds of kindness.


Additionally, it is crucial to experience sadness in order to understand what is right and wrong.

If you realize that your past experiences have taught you a valuable lesson, you should avoid making the same mistake again.

Even though we feel sad at that time, it is necessary for your survival only.

For instance, you must have experienced the death of a friend or family member.

Perhaps the result of an alcohol or smoking habit. whatever the cause may be.

You felt so depressed at the time, and although it might still exist today, you took this experience as a lesson not to smoke or drink.

Therefore, whatever occurs is solely for your survival.


The way happy hormones give us happiness, the sooner these hormones drop and we don’t feel that happiness again.

As if you went out to eat at a new restaurant and really enjoyed it; you were glad afterward; but if you went there every day, after a few days your mind would grow tired of that meal.

You won’t experience the same level of pleasure you had at first, so you’ll need to find another way to satisfy your needs.

And it’s only for the better because if you continue to find enjoyment in the same things, you won’t be able to think of anything new and you’ll remain in the same place.

You strive to advance and conceive of new ideas to get this bliss.

It is your prior experiences that your mind stores, therefore you do not need to constantly tell it what is right and bad.

Additionally, the mind makes an effort to keep you away from something if it has caused you trouble in the past or if you have such an experience.

Similarly to this, your brain encourages you to work hard if you received a reward for doing something that made you extremely happy.

But if you get that reward without doing anything, then your mind will show you such ways, that’s why you should always work hard and take the reward only by walking on the right path.


Dopamine strategies: Learn to enjoy each small victory you achieve; if you think that if you achieve large accomplishments, only then will you be happy, then you will never be.

To reach your goals, practice taking daily little steps and celebrating each small victory.

Endorphins strategies: Always keep laughing, when you do, your mind will find ways to make you laugh. Laughing heartily releases endorphins.

Make fitness enjoyable by trying new activities and locations.

You should cry occasionally since it helps your heart feel better, but don’t keep crying all the time.

Oxytocin strategies: Making yourself trustworthy will release oxytocin. Try to learn to trust others as well.

Additionally, receiving massages releases the hormone oxytocin. For this reason, maintain scheduling massages. You can also arrange for your friends to massage you and vice versa.

You will always be joyful if you do this, and your body will release oxytocin.

Serotonin strategies: Learn to take pride in your work, and don’t let yourself feel small.

Additionally, try not to worry too much about things you cannot control.

Your mind becomes frustrated as a result. Just focus on the things under your control.


Create a daily schedule that you may follow to discover happiness.

Although it will be challenging at first, as you advance, you will feel happy. By doing this, you can constantly maintain a positive outlook.

Create a new habit that makes you joyful each day.

Form a habit that you should keep up for 45 days; doing so will help you find the work easier. Try not to stop doing the task before that point; if you do, you must restart from day one.

Try new things; your mind is naturally drawn to them, so constantly remind yourself that you are learning and doing something new.

Always choose the long run above the short run because temporary may bring enjoyment in the short term, but the latter is not worthwhile over the long term.

Therefore, always choose the long term. It may seem boring at first, but it will be worthwhile.


Do not consider yourself responsible for others’ unhappiness and in the same way do not give responsibility to others for your own unhappiness.

It is entirely up to you how to maintain your happiness.

Keep in mind that knowledge is power, therefore you should know how to be happy.

If your happy hormones drop, you should also know how to get them back.

You are the only one who can do this; if someone else tries, it will not work.

Because your brain is only focused on you and not on others, if you keep yourself happy, other people will naturally start to feel happier as well.

So, start being happy.



Mirror people who already have the habits you want.

Find someone who already has the habit you want to develop and observe them.


Your brain wants all four of the happy chemicals.

You undoubtedly excel at some remodeling projects more than others, so it can be tempting to pick one in that area.

graft You can attach a new branch to the roots of an existing joyful circuit.


Your brain only has a limited amount of energy.

Exercise, rest, and a healthy diet can improve it, but it will still be limited.

More energy is used by new activities than you anticipate.

You promise to make that energy available when you commit to a 45-day rewiring project.

You will find excuses to break your daily commitment if you run out of energy before completing it.

Make your new habit the primary priority with your energies for 45 days, even if that means letting go of another one.


Repetition is easier to tolerate if you can make it fun.


Because it can only comprehend a limited number of stimuli at once, the brain constantly divides things into manageable bits.

The majority of the time, we aren’t aware of this chunking method, but you can use it consciously to feel like your issues are more manageable.


Build a new circuit before you need it.

Before you get tired of your current vegetables, try some new ones.

Do someone a favor before you need a favor from her.

Develop new sources of pride before you retire and get wrinkles.

You might feel too busy right now to do these activities, but once they start to release happy chemicals, you’ll be pleased you did.

Plan to “do something” rather than wait for the feel-good chemicals to arrive.

Thank you for your time.
