Advice for 23 year old?

Hello all,

I’m a 23 year old Civil Engineer that has passed my Fundamentals of Engineering exam. I currently make $60k a year in a low cost of living area. I live with my parents and have almost no expenses and no debt. Once I get my Professional Engineer’s license, I’ll easily be making at least $80-90k, and eventually getting to $100-130k. I’ve saved about $40k and want to begin investing. I’m maxing my 401k contributions. I’ve read that I should max a Roth IRA at $6k a year. How do I go about doing this? What other advice do you have for me beyond that? Thank you for your help.
