How do I stay committed to a goal when I feel like giving up?
Fix your heart on the goal
A yogi was mocked for trying to climb a hill, and he answered that his heart was already at the top, so the body would follow. Where your heart is, you will go. Fix your heart there and it keeps pulling you in the same direction.
I have already put my heart up there. The rest of the body will follow anyway, so don't worry about me. My heart is already up there.
