However, all smart people are very likely to know these three things regardless of what field of expertise they cultivate.
1. Smart people know how they will get better at their "art" each day.
2. Smart people know how their "art" will help someone else.
3. Smart people know that in order to get (and remain) "smart" it takes effort and grit. Becoming really good at anything requires pushing through the tough spots where most people give up. Smart people know and live this.
