Be a good person but don't waste time to prove it.
In life you should be good person but never try to prove it, that you are a good person. Because the people who feel you are a good person they will feel the same even if you don't tell them and the people who think you are a wrong person, they will always feel the same, what ever you tell them and do for them. So don't try to prove that, you are a good person and live your life your way.
Be a good person but don't waste time to prove it.
