Arriving late to something feels like evidence of a deficiency, when usually the only real difference is a starting date. People who learned to swim, drive, cook or type at ten had the chance at ten, which was not a decision they made. The embarrassment is about being seen as a beginner at an age when you were supposed to be past it, and it keeps people away from a skill for decades over a few awkward weeks.

Pick the thing you have avoided because you feel you should already know it. Learn it somewhere you are not known, or with one patient person.
