I am capable of any physical feat I wish to do!

A person who can't manage a single push-up today can usually do ten inside a couple of months. Nothing was unlocked. The capacity wasn't hiding anywhere; it got manufactured, on the knees at first, badly, three mornings a week.

Capability reads like a fixed property of a person, which is why I'm not built for that sounds like a fact instead of a schedule. Mostly it's a schedule.

The honest version carries a footnote, since bodies have real limits and they differ. But hardly anyone is anywhere near theirs. The gap between what you can do today and what you'd like to do is, nine times out of ten, a stretch of weeks nobody has spent yet.
