how much money will you require to be happy

Infinite

If you are looking for happiness in money, then you will never be happy. You will sacrifice youe family, your happiness and your health in pursuit of money, only to realise when you've lost everything else, that money never brings happiness anyway. You can't eat money, you can't drink money, money does not love you, and money can be stolen any time. Money is a TOOL. It should be treated as such. When money becomes a tool to help you progress in life, then you start discovering happiness, because you devote time to your family, friends and health.
