How to know if trading is for you?

I have been very interested in market, derivatives, and just how the world economy is structured from a very young age, got into the right school, and now it’s almost time to recruit for these roles. Just curious how you can make the bet on yourself and know you will perform well as a trader, especially at these more prop focused jobs. It’s one thing to go FICC or something at a bank where risk is less, but what if you have the opportunity to go to a small prop shop where you have the potential to make 7 figures but also to make close to nothing, lose the job, and not have a BB on the resume. I guess I’m asking how yall where able to “pigeon hole” yourselves by going into FTR/VT or physical energy trading, for example, whether at a prop shop or merchant house and have the confidence that it would work out regardless? I mean you can’t KNOW your gonna be a head honcho until your sat in the seat.
