I think you could. In some sense "easily". It may be about finding that thing you're naturally so interested in or otherwise drawn to, that the months figuring out become a type of driven joy, and so the willpower kinda automatic.

And if you find it, don't judge what it is or worry what others might think - or even necessarily tell anyone. Sometimes the most motivating things are highly personal, as with the OP; a significant part of their childhood.
