Exceptional outcomes often begin with refusing ordinary sloppiness.

Remarkable results usually do not begin with a remarkable idea. They begin with someone declining to accept the ordinary carelessness that everyone else waves through, the unchecked figure, the unread draft, the detail left approximate. Nothing about that is brilliant. It accumulates into a difference that looks like brilliance from outside.

Pick one form of sloppiness you tolerate as normal and stop tolerating it. Just one, applied every time. The effect is slow and it compounds in a way that a single burst of effort never does.
