I am capable and confident.

Those two words are usually assumed to arrive together. They don't. Capability comes first, and confidence lags it by months.

Think about learning to drive. There's a stretch where you can genuinely do it — safely, competently, in traffic — and still feel like a fraud at every roundabout. Nothing about your driving changes on the day that feeling finally lifts. The skill was already there; the feeling was simply slow.

If you're waiting to feel confident before acting as though you're capable, the order is backward. Act from the evidence rather than the mood. The mood catches up, usually without announcing itself.
