Money is a factor - weighted differently for different people. E.g. person A generally wants to be happy in their job, but needs $100k to maintain their lifestyle, pay the mortgage, not worry about bills etc. If paid $100k they wouldn't jump ship. Later, person A has a baby. Well guess what happens next. Person B also wants to be happy in their job, but they also want to invest in stocks for an early retirement. They get an offer at a stressful trading job paying 3 times their current salary. They think it is worth it in the short term so they go for it.
