2 million dollars - the difference between 14 and 12 - is alot of money. I'd move over it.
And once again, a very small percentage of athletes actually get to that level.
You choosing to take less money because you assume having more money will make you unhappy has far less significance than you think it does.
The extra 4 million is going to make a 4 million dollar difference, so yes. Most people will notice 4 million dollars moving no matter how much money they have. In fact, if I had 20 million and I could have had 24 million I would probably kick the closest small, defenseless organism and then some.
