Just to piggy back off basketball and practice, this video of Steph Curry practicing shooting 3s for an hour from a few months ago just puts things in perspective for me.

A best ever at something doing the most simple drills for an hour.
I have in my head I suck at basketball but Curry takes more practice shots in that video than I have in my life.
