You can know you’re good at something without announcing it. Quiet knowing is the strongest kind.

Skill that needs constant confirmation is being propped up from outside, and anything propped up from outside can be knocked over by one offhand comment. When you know what you can do, a poor review lands and you stay standing, because the knowing did not come from reviews in the first place. Announcing is often an attempt to get that certainty faster. It works for about an hour.

Pick something you are genuinely good at and let one chance to mention it go by. Notice whether it still feels true with nobody confirming it. The answer tells you where your confidence is currently stored.
