Upon consideration, I think maybe it's clearer in the inverse:
If you have to worry about how well you do it, it's not worth it for you to do.
I think this applies equally well to things doing the things you love doing - raising kids, making art - as it does to clearing blockers and doing-things-what-need-doing.
Note that the "have to" is a key part - most people will and/or should actually worry about how well they do - the difference is whether you're required to worry.
This definitely doesn't apply to all situations - it missed the entire field of "things you're good at" - but I found it decently insightful for my personal life.
