Welcome! You've taken the first step in that you recognize you want to take action. DW and I are in the same age bracket, different circumstances but the same desire to finish up w*rk early. First suggestion, read and learn all you can if this really interests you. You'll find there isn't just one path to FI, but many and many pros/cons of each depending on individual situation and needs. Second suggestion, find the path that works for you and build your strategy around it. Ignore the hype of X investment is the best, Y fund is the way to go, do X with your cash... Find, based on your learning, what is good for you and keeps you motivated over the years- end of the day no strategy is good if you can't stick with it.
DW and I focused on paying off our debts (excluding mortgage) before we heavily started investing beyond our company 401ks etc to get matches. We refi'ed our mortgage down to a 15yr with low interest rates to work on getting that done quicker as well. From there focused on high quality dividend paying stocks and low cost index funds. This was just our path but may not be appropriate for you or your interests. Keep asking questions, keep learning and best of luck!
