Great master Lao Tzu says that 'The Master has no possessions. The more he does for others, the happier he is. The more he gives to others, the wealthier he is.'

If the weather is sunny, it is good; if the weather is rainy, it is good; if it is foggy, it is good; if it is stormy, it is good; if it is damn cold, it is good; if it is damn hot, it is good! With a positive attitude of mind, all becomes good!

Do not focus on being happy, focus on doing something useful; afterwards, happiness will flow towards you!
