You can admire people without putting them on a poster. Heroes have bad days too.

Admiration works better in pieces than in whole figures. Lifting somebody onto a poster means you have to defend all of them, and then their ordinary failures feel like a betrayal of you rather than a Tuesday for them. Taking the specific thing you want to learn and leaving the rest is fairer to them and more useful to you.

Pick somebody you look up to and name the one quality you are actually after: their preparation, their patience, the way they treat juniors. Study that. When they turn out to be flawed elsewhere, you will not have to throw out the lesson.
