Hey Aaron!
I think it is awesome you have your eyes set on the future and want to set yourself up for when you feel you are ready to invest.
It seems that you are looking for a "mentor" that will help you learn the fundamentals as you progress which is great; however, a lesson I learned is that it is difficult finding a reputable mentor without offering some sort of "value." One thing I find almost ALL successful investors value is their TIME. If they are going to exchange it, then I would generally assume they are more willing to do so for something in return. Maybe that is bird-dogging deals once you learn how to evaluate deals, maybe it is cleaning up their flips/rentals, etc. Get creative!
Since you asked for constructive things you could do, I would first suggest learning as much as you can from BP. There is quite literally EVERYTHING you need to know, short of actual tangible experience, on this site for someone to get started. @Brandon Turner hosts weekly webinars which hold SO much value. The forums are a great place where you can virtually rub shoulders with giants who have tons of success and often openly share what they have done.
I wish you nothing but the best!
