How do you learn drafting?

I’ve been playing the game for about 4 years now. I got 40k trophies and I’m hard stuck mythic for 6 seasons now, and I always feel like my mechanics aren’t the problem but the brawlers I’m facing off against, though I don’t fully disregard the option that my mechanics may be holding me back.

I’ve tried watching tutorials on how to improve drafting, but whenever I apply the tips I feel like I overanalyze scenarios and end up choosing brawlers I’m not too good in/not good in solo queue or mythic.

I’m also extremely inconsistent in ranked. Sometimes I’ll reach 2 games away from legendary just to tilt down to barely mythic 2/high mythic 1.

Any advice on how to draft better?
