You know guys w/ net worths of $22 million and $66 million who are in the gym business?
yes.
got in later in life. both as 'favors'.
one makes 99% of his income out of the gym (avocado orchards, property/real estate/developing) but spends 99% of his time in the gym trying to make money (he didn't).
the other is just a money man. Made the majority of his money in lettuce and horses. spends maybe 30mins in the gym each day and has no interest in day-to-day operations. actually a little less than 66 mil, but over 50.
