Me and Kay might fight a shitton about my personality but she's probably got the best mind for Mafia here (after me of course). She's absolutely correct here.
This is how I improved. I went out, I did shit, and most importantly, I fucked up a lot. Don't believe me? Look at Mafia Round 3 or Mini Mafia 5. Old games where I completely fucked up but I learnt from them. If you don't ever want to put your ass on the line because you're worried about looking stupid, you'll never improve. If you're willing to risk it all to win it all, the rewards are that much sweeter.
