Nice post and plan!
I am a dad, but I am really not poor anymore and my kids are grown.

All I can tell you is don't stop planning. Keep on coming up with ways to get income however you can. I have supported my kids fairly well, but to this day wished I had done more. I especially wish I had done better in the preparing my kids for being better at money than I was (fell a bit short on that one). Nice to see you are planning for that
