Checking yourself is a pit stop. Staring at yourself all race long is how you finish last.

Self-examination has an ideal amount. A brief look at what you are getting wrong is one of the most efficient things available, and the same activity extended indefinitely becomes its own obstacle, since analysis feels like effort while producing nothing. At some point the useful move is to continue with what you have. Reflection exists to serve the work rather than to replace it.

Give yourself a fixed window for review and then close it. Decide on one adjustment and carry it into the next attempt. If you catch yourself reviewing the same thing twice, take that as the signal to move.
