The problem with a high earning career as a professional athlete, is that you have to average their salary over their lifetime, and their earnings drop really fast after they hit their mid thirties.
At the end of interviews when they ask "Do you have any questions for me" I make a point of asking what they felt was good about my interview and how they think I could have improved it. Most of the time, they refuse to answer that question. I think it's probably a bad idea for me to do this.
