In hindsight, the happiness you felt as a kid was all fake.

When you're a kid, you are mostly naive and ignorant about everything. You are happy because you have no idea about reality. The environment, the economy, your future, your sex life - all is fine, you don't worry about these things. Anywhere you go, you are always accompanied by two people who are responsible for your life. You are happy not because you have a happy life, but because you are ignorant about everything and have no responsibilities. Such a life stays for 10-15 years and then one day it's all gone and you are thrown into the "real world."<br><br>When you are an adult, the poor become more miserable. They have to work, they have to struggle to survive. The rich become even more happy. They have a life filled with luxury. The middle class stays somewhere in the middle, not happy not sad, only stressed.
