If you're not "used to" being successful in something, it's not wrong to be scared of it. In my line of work, I've achieved success of some sort, and it indeed is scary. I could never imagine it could go so well. For whatever you're having a success with, be humble but continue the same path that led you where you are at now. It would give you respect from people around you in that topic of whatever field, meaning if you screw up something, you're likely forgiven, granted that it don't tear down the entire thing. This is also something you can see among the so-called "elite": someone successful screws up; they are probably forgiven and someone would help you clean up. This kinda smells Epstein, but whatever.
