New Trader

I traded a bit when I first turned 18, quickly realized, it can make great returns, but you have to play with real money to get anywhere. I’m 23 now committed to fully learning, and have a 3 account split. 1 Roth (strictly retirement) 2 technical trading ( testing waters) 3 fundamental trading, I one day hope to leverage into PE I am a novice obviously, and don’t have direction, any advice, study materials, working towards an MBA in finance. I work sales and have a decent amount to invest but I really woulda like to stay away from online gurus as much as possible. (Unless, I get to or know them on a personal level)
