As a dominant visually wired guy, I have found my “portfolio of evidence” to be helpful for these moments.
The portfolio documents photos of wins, when I overcame (predominantly mental) obstacles that were a stretch or a fear.
The photos could be compiled in an album, or a slideshow or they may be displayed on a pin board in your strategy room.
The evidence will shut up those doubtful questions with definite proof that you can because you have!
