The reward for great work is more work, and I find that saying that maxim to the right person, the kind of person I want to spend time with, their eyes go wide and they understand it immediately. That the reward for great work is not money, power, fame. It is the privilege to get to do more of this thing that I love doing.
I love this because people should just do what they're supposed to do. People overestimate how much they'll enjoy retirement. Do what God designed you to do—it's that simple. You'll have more fun and more longevity doing it.
