How can I leverage Hard Work?

[Dan Griebling]

All my life I have created success by outworking the next guy. That has served me in athletics, the military, school, and the traditional work place. Right now, I am aggressively paying off all my debt (mostly some student loans) and then immediately rolling that cash into rentals. I will be debt free December 2020. After that, I will have 4k+ in cash flow per month to invest. I currently own a duplex which basically breaks even on cash flow but which I had instant equity in (not a bad deal but before I knew what I know now). Here is my question. How do I best spend my time as I pay off debt? I have thought about working in my spare time as a handyman or even managing rentals. Both could create cash flow and help me learn the market and get to know folks. Alternatively, I have thought about doing nothing but immersing myself in learning for the next year and a half. I thought about getting a realtors license (mostly so I can see MLS listings) and I have even considered looking at hard money loans IF the numbers work --- but with their rates, I simply don't see anything that makes sense on paper. So, again, any advice on the BEST way to spend my time as I pay off debt and save up my down payment for my next investment? Working, learning, networking, other? Thanks for taking the time to think about this, I appreciate any thoughts any one has.
