Seriously it is difficult to be 100% happy on this planet, as we have high expectations. But it is not impossible! In our past years we learned how to be happy and how to control our mind or actions.
We need to be positive all the time and hope for the better future. Be patient and never give up. Every successful person gained success after many failures.
Alone we cant do it, but together we will. So lets work together toward the real success :)
