We all have friends who have delusional greatness in their subconscious, and because of that, they never actually get better. It was very important for me to have my dreams crushed, to detach my ego from my ability, so that I could objectively say, you're not good at this. You're not good at this. I think it's very important for every person, if they want to accomplish something great in a career, to have a season where they actually take a careful inventory of what their actual abilities are.
