I think that’s a great point. Vision is critical, and willpower helps move the machine, like fuel.
But I still think commitment is a force that pulls the machine forward even if it’s out of “gas.” It’s what enables a person to accomplish feats they thought were impossible, even surprising themselves (because they thought their tank was “empty”). People can still accomplish great things when they’re out of “gas.”
There is a delicate balance of both willpower and commitment in these endeavors, and I appreciate the back-and-forth with this!
