Many times people start criticising other without any strong reason. They start making issues for small things. They even try to damage your emage.
So if it happens with you, try to be cool make your self busy on work. Try to answer criticism by your work not by words. Don’t think negatively be always positive. Try expend time with people who have positive thoughts.
Your life is very important. Its every minute is precious. Don’t west your time in negative things. Try to do some thing new in life. If you have time expend it with children , nature.
You can not charge the world but you can change your self. New future is waiting for you start today some thing new.
