Willpower

Which quality found in childhood has been shown by science to be the single greatest predictor of success in adult life?

Strong willpower is fixed quality determined at birth. It cannot be built or improved upon. Either you have it or you don't.

Willpower never depletes, it is always there in abundance, its just a question of learning how to tap into it.

Willpower is essentially our ability to think about what we are doing and make sure our immediate actions are in line with our long term goals. Which of these makes that very difficult.
