4.Money before passion Sometimes a job may simply be a way of making money rather than a way to be happy, but there are always things that one can do to make the experience more pleasant. Most of the people put money before their passion. No matter how much money one makes, they think they need 20 percent more to be happy. A recent research shows that people who choose career they are passionate about are happier and make more money, than people choosing career based on the paycheck. It's the worst decision one can ever make.
