Why we are here? We want money? or we want be happy? money buys happy?

I dont agree with you that money biys happyness.As money can only buy things which sometimes gives happiness and also sometimes gives sorrow.Money cant buy everything, as then every welthy person would be happy.While in relaity welthy people are most unhappy as they are all the time engaged in securing their money.The secret of happiness is mental satisfaction.And mental satisfaction can be achieved in many ways like helping others, doing some good thing, etc.
