Set reasonably attainable goals, then once you’ve accomplished it set a new reasonably attainable goal.
Frequently reassess whether the goal you originally set is still actually the goal you most want to be pursuing. Sometimes you set a goal and at some point later realize it isn’t worth it or will never actually succeed, in which case you’re much better off abandoning that goal so you can instead pursue a goal that will actually succeed.
That’s bad advice anyway.
