Also per Mike LaTulip who in an Illini Inquirer podcast said that it isn't a matter of just getting into the gym and shooting free throws for hours and hours but is more of a mental challenge. One has to go to the free throw line thinking along the lines of "You fouled me, so now you will pay for it with my two free throws". In other words, a positive attitude where you approach the line eagerly to make those free throws. You can't even say, "I can't miss these free throws" since the word "miss" is now in your brain and it will affect your shot.
