Always do your best.
What you plant now,
you will harvest later.
All external motivation is temporary. External motivation is the kind that may wake you up, but it will not keep you awake for long. External motivation is motivation that comes to you from the outside. It may, and it often does, influence you to make a change, it cannot however make the change for you. And it cannot keep you from drifting off course, when the motivator is gone.
