• Cook is a very private individual who wakes up early and makes time for exercise.

• He's a self-proclaimed "workaholic" who gets up to 800 emails a day.

Apple CEO Tim Cook's yearly earnings are directly tied to how well the tech giant performs in the stock market.

So judging from the size of his bonus, it's been a good year for Apple. Business Insider reported Cook raked in a grand total of $12,825,066 in 2017.
