Currently on T and I can definitely say my personality has become a lot less agreeable. This doesn't make me a bad person per-say but I feel so much stronger and confident about saying no to people and surprisingly it helps people think I'm way more confident overall despite some of my emotional shortcomings I'm dealing with more privately. This is going off the Big Five personality theory when I say this and probably the best way I can think to describe it. I've noticed a bunch of these traits on the list you provided can describe me but a lot of it also probably has to do with me pursuing a future as a volunteer fireman since I'm working out and trying to get strong physically and emotionally to prepare for it and it's important to me because helping others gives me purpose.
