The knowledge one acquire in school is so much different than the knowledge gained by experience. Once learned something from experience, it can be used to solve new problems in life. Albert Einstein was one of the most intelligent man ever lived in this planet, and he claims the only source of knowledge is experience.
When we envy others we only envy some part of their lives. It is so easy to find the good things in other peoples lives and neglect the bad ones. We would like to have a “hand picked selection” of good things and then we find our-self depressed if it does not came about. You cannot find happiness until you envy others.
There is a big difference between the real problem one faces and the imagined anxieties about this problem. People tend to overrate their difficulties and create imaginary problems in addition to real ones. You have to make the question: do you really want to solve your problems, or just want to create more excuses?
People tend to think their happiness depends on other people and circumstances. We think if our parents/ children/ colleagues behave differently we will be happier. The truth is we can’t change them, but we can change our attitude and how we react. Those people who find happiness within themselves are generally more happy than those who want to find it in other people.
