It isn’t a matter of “willpower”, but “carepower”. 

What’s the difference?

Willpower — typically we are told by others that if we just had more “willpower” we can do it. But the problem is that we are typically lectured on what we should be working hard on. But typically, we don’t exert much willpower on things we don’t care for. 

My suggestion:

You will naturally expend huge amounts of efforts on things you actually care for. 

Thus, think about what you truly care for, and expend epic energy and strength on that!
