Big talkers get tested. Quiet performers get trusted with the ball in the fourth quarter.

Claims invite checking. Announce that you are the best at something and people will find a way to see whether it holds, usually at the worst moment. Doing it consistently without commentary builds a different kind of reputation, one nobody feels the need to test, because it has already been demonstrated. That is the reputation that gets handed the important thing.

For the next month, promise less than you intend to do and then do slightly more. Skip the announcement and let the result speak in the moment it matters. Reliability is boring to talk about and extremely noticeable when it counts.
