The most people is living with anxiety during their life. I think this problem's reason is the most people is conditioning self to be successful or to be happy person. These concepts are quite relative and it is so hard to right results.
Success or happiness is not aim of the life
Success or happiness is not aim of the life, but usually we are living as to be so. So many people is tired for to be success or to be happy. if you look for happiness or success in your life, then you would be so tired and unhappy.
Experience is everything
If you ask me my opinion, i say that experience is everything. For example your family life is a experience, your job life is a excperience or your marriage... all of the things give you a experience for your life.
Enjoy the moment..
Also another point is to be live at the moment. No matter how difficult life is, it is important to enjoy the moment.
You don't tire self for meaningless things and enjoy the moment..
