Looking for advice from those of you who've been at this a while and/or have investment experience.

Ok, so...I have a 20k bankroll, plus 20k savings. My current employment allows me to save roughly $4000/month after all of my expenses are paid, and leaves me with a bit leftover in my checking. I don't know much about investing, but I do know my money isn't doing much for me in a savings account. So...

Goals:
1. Increase bankroll to give me ~$100/hr EV with little to no RoR

2. Put my savings somewhere that it will grow, preferably keeping up with or outperforming inflation.

Given these goals and my situation, what would you suggest? Please, if you have the time make a serious and thoughtful reply or PM me. If not, friendly banter only please. Thanks guys.

P.S. if you know a good book that touches on this subject, I'd love to read it.
