Practical Steps to take before graduating college

[Jared B.]

I am currently a college student going into my sophomore year. I will have little to no debt graduating out of college. I know that I want to House Hack (duplex) to start my real estate investing journey right out of college (and later invest in multifamily properties after the house hack). Right now, I'm working the summers to pay off small student loans and saving a little. 

Are there any practical steps I can take to continually grow and develop before I start investing in real estate? I've read a few books and have talked with a few family friends that are either realtors or house flippers, but I want to get more involved before I am able to gather the capital necessary to start investing.
