Compete against your own unused ability.

The most frustrating competitor is the version of you that could have done more. Not a hypothetical genius, just you at full effort, which is a realistic and uncomfortable standard. Most of the distance between where you are and where you could be is unused rather than unavailable.

Pick one area and ask what you would do differently if you actually used what you have. Then do one of those things. The gains from unused ability are cheaper than the gains from new ability.
