do one thing-

Paulo Coelho:

Even if you were to study your own life in detail and relive each moment that you suffered, sweated and smiled beneath the sun, you would still never know exactly when you had been useful to someone else.
A life is never useless. Each soul that came down to Earth is here for a reason.
The people who really help others are not trying to be useful, but are simply leading a useful life. They rarely give advice, but serve as an example.
Do one thing: live the life you always wanted to live. Avoid criticising others and concentrate on fulfilling your dreams. This may not seem very important to you, but God, who sees all, knows that the example you give is helping Him to improve the world. And each day, He will bestow more blessings upon it.
