What motivated you the most to keep pushing in med school?

Will be starting med school in few months and I am wondering on what motivated you the most, other than the fact that you don't want to end up homeless with countless debt lol? what's more challenging, the difficulty of concepts or the amount of material demanded to learn? How did you keep yourself on track and motivated?
