To be happy.
But bear in mind that happiness, cannot in itself be sought after as the main objective, because true happiness is a byproduct of life. Helping other, being faithful to your beliefs and your family, working hard, enjoying rest etc, will make you happy - the mistake people make is when they leave these things to one side in pursuit of 'happiness'
The same thing is true with Money. If you seek money, as your main objective it will lead to 'all kind of evil'. If you work hard, however, and are careful and wise with your money, you can enjoy it and be happy, and use your money to give your family and the ones you love more oppurtunity and time to relax.
