Learn to be thanksgiving.
If there is rich, there is poor. If there is healthy, there is sick.Life has its brightness and darkness.But whatever the objective situation is,you decide whether you will be enjoying the time.
Every people has its good sides and bad sides.But we only have one preference to them,like or unlike.Sometimes we like somebody truly but we don't like what he do so we tell ourselves he is so bad,I won't like him but in fact we do.When we are mad,we tend to ignore the happy times we spent with him.No one is perfect while there are many important ones in our lives.So,in order not to be regret,learn to be thanksgiving and cherish.
