If you use up your motivation, it's gone. The gas tank is empty, depleted.

No. Willpower isn't like running out of gas. Willpower is more like an emotion. We don't run out of fear, joy, anger, love...but they do ebb and flow.

I challenge you to THINK about how you're THINKING. We can reframe your perspective so that you don't need to increase or muster up motivation with extreme effort.
