What qualities, if any, did you see in candidates that just screamed “future PJ”? Was it physicality or their ability to lead others?

I have absolutely seen guys who I thought would make it and did. The traits that I always see in guys who make it are, first that they are all about the team and put in all their efforts to help out with whatever they can. Second, they are always in shape and physical studs because if you can get through the smoke sessions with no problem then you can take care of your guys. Lastly, the biggest thing I see from guys is when they are able to stay calm and cool when we tell the team to start doing pool work in which they might pass out. This shows that they are 100% committed to accomplishing the mission no matter what it takes, they have burned the boats.
