这个世界最伟大的发现是，人可以通过改变其内在态度来改变其外在生活的方方面面。

There’s a choice that we have to make as people, as individuals. If you want to be great at something, there’s a choice you have to make. We all can be masters at our craft, but you have to make a choice. What I mean by that is, there are inherent sacrifices that come along with that. Family time, hanging out with friends, being a great friend, being a great son, nephew, whatever the case may be. There are sacrifices that come along with making that decision.
