How to enhance happiness?

There are four hormones connected to happiness. These are
1. Endorphins: These are secreted when we do exercise and while laughing. Endorphin help us to bear stress and pain and thus we enjoy the exercise.
2. Dopamine: It is secreted when we get appreciation
3. Serotonin: It is secreted when we help others selflessly or educate them.
