I agree. Set realistic goals. Give yourself permission to exceed them, but don't make it mandatory.
And I'd also add, short-cycle goals. Get feedback, and go from there for the next round. For example:
'During my next three afternoon study sessions, I will try and add a brief to medium prestudy for the next section in the math book.'
You might find that this doesn't really work for one reason or another. Or you might find it works like gangbusters! And either way, you get feedback and you roll on from there.
