It becomes effortful to *not* do it. It pulls you in and demands you keep working.
Discipline is fighting yourself.
Wasted energy. Wasted creativity.
Put that instead into figuring out what you actually most want.
Solve problems in doing what you want with reason, not force.
It sounds cute and simplicistic — like meaningless motivational self-help talk — but the world really does work this way.
Problems really are soluble. What's stopping you really is conflicting ideas. Force is trying to reach answers/truth using brute authority instead of reason.
"I've tried everything! Self-discipline, Beeminder, social media time-outs, Tony Robbins, waking at 5am... Nothing seems to work!"
This is why Karl Popper criticised revolutionary epistemologies:
All knowledge is built on existing knowledge.
That's the structure of how epistemology works: you start with a problem—which is inherently based in existing knowledge—and you conjecture variant theories, which are also based on (refer to) existing theories.
