Would you please thank God and be statisfied with what you have...
Be ambitious and try to get more but consider the more as a bonus. Your life shouldn't be planned on the bonus, you happiness shouldn't depend on the bonus. Don't let yourself go after the temptation of endless power and money, and know that with everything you get, there is something you let go of, so it is better to let it go yourself!
Real Happiness is in giving, not only getting!
