I'm not scared of success for the most part or really at all. I just don't want to be trapped in something terrible or horrible.

It's more or so control with me. As long as I have control and the ability to destroy (if something goes wrong) my success or what I've done I'm fine.

I don't get scared.

I have fear though definitely or I do worry that something could go wrong.

cherry pick really fast on this one to cheat a bit here...

150 foot tall robots - It has the ability to travel at speeds of 2,500 MPH. It can also do 100s of other things.

The problem is if it becomes a "war robot" and I lose the ability to destroy it or someone else gets it and I lose the ability to destroy the war robot. I don't want to be responsible for that alone if something were to happen and see that as a major failure.

I'm not scared of success, but I'm fearful of what may happen.

Sounds like you don't want to be a target...

In my experience, the more successful you become, the more you are open to people looking to take you down.

Success has consequences that generally involve undesirable compromise.

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.
