The sharpest knife in the kitchen is useless to someone afraid to make the first cut.

Capability that is never used might as well not exist, and hesitation is a much more common limit than ability. Plenty of highly capable people never start, waiting for certainty about the first move, and the capability sits there unemployed for years.

Make the first cut on something this week, badly if necessary. The first move is the whole difficulty, and it is almost always reversible. Skill without initiation is just potential wearing a better name.
