Bro, never let someone else's opinion define your passion and your own opinion and shape the value of it. Also, it's not a bad thing to be wrong sometimes.

What I have learned over the years is that I should give more of a less fuck about what others think and stop asking for validation from others. This way I can stay true to myself, which also means to respect every other opinion, good or bad.  Because that opinion is just based on their own experiences as well. You've set the bar high for yourself, meaning you're too hard on yourself. Which can be a good thing for motivation, but never underestimate yourself, and be thankful that you aren't there yet where you want to be. It would be boring as fuck otherwise, right? 

How many times have you found yourself being right about others based on your own gut feeling? Probably many times, and that is a talent many people do not have. I can only say that you could (and should) rely more on your own gut feeling for that matter and stick with that plan and value  (unless you have been wrong about people xD).

You got a great sense, righteous and judgemental. It can't be too hard to start believing you actually have a talent yourself, but it might take some time. I've been there my entire life and it consumed me entirely, living in a bubble that wasn't good enough. Yet it was so refreshing when I found out about my own talents.
