Differences between Retail and Prop Trading

I've been in the markets for a little over 2 years, and would consider myself profitable. I've studied good traders and been a part of a legit mentorship group. I started actively trading stocks in my IRA from my last job in July/August of this year, and currently up about 40% YTD. I'm still making mistakes, and don't think that will ever end, and need to work more on journaling. At this point, I feel like I have a pretty good idea what I need to do and characteristics to have to be good. My question is what would it be like to join a prop trading firm? I'm currently a scientist, and I don't love it. Most of my time is dedicated to learning about the market. It's the first thing I do and the last thing I do every day. While I don't feel super comfortable trading independently yet, I wonder why not make trading my job, and surround myself with pro graders to learn from them? That said, I understand the burnout rate is high, and it's a stressful job. But trading is hard, and I'm still here. So I want to know what it's like at the next level. Any insights would be appreciated. 

btw. I realize there's a wide variety of prop shops, but I'm mostly looking at ones with a decent base salary. I don't care so much about getting rich from prop trading so much as the learning experience.
