Do not allow your happiness to depend on someone because that someone may not always be the person you believe he/she is.
Be humble to admit your mistakes, intelligent to learn from them and mature to correct them.
Do not measure your wealth with the money that you have, measure it with the things that you will not change for money.
The world changes with your example, not with your opinion.
Patience is the strength of the weak and impatience the weakness of the strong.
It is not that the happy persons who are grateful.. it is the grateful persons who are happy.
