Great people often seriously experienced their mortality or frailty in some way. John Coltrane had four family members die in three months; Stephen Hawking contracted that motor thing he has; countless great musicians have lost a sense. I can see how experiencing something unexpected and tragic would kick you in the pants to go all in on what you love, and do it now! These people understand their power and their freedom through their commitment. Isn’t it ironic or profound that we can’t or absolutely would not choose to have such an experience, even in exchange for greatness? In order to do what you love with the passion of greatness, would you choose to have most of your family die? Could you give up sight, hearing, or movement? Even if you did, would you not be filled with guilt or regret rather than experiencing the preciousness of life? In this sense, nature blesses and curses at the same time, seemingly at random; we cannot invoke it or avoid it.
