Everybody wants happiness nobody wants pain, but you can’t have a rainbow without a little rain. You can only praise the good if you have passed through the bad. Many great personalities have tried to improve the mankind by helping poor people and the ones in need; But we still are not free from poverty and several other problems. Without such problems mankind is incomplete. The reason behind this is if there was no poverty we would never have known the importance of money. If we had no problems we would have never thought about God. The good is incomplete without the bad.
No one is perfect. People say and believe that there is something good in everybody and also there is something bad in everyone. But they are not ready to accept that. When they have a bad habit they say that there is something bad in everyone; but when someone else have a bad habit they are not ready to accept that. Acceptance is one of the most important factor in a relationship. If you want to live with a positive nature of a person you should also accept his/her other side.
So, stop complaining start living.
