You have made the first and most important decision. You have stopped waffling and are ready to DO THIS. I made this choice back in June of 2020... I had naively planned on being on the road that Dec ( bwaahaahhh on me) As it turned out I managed to head out this past January. *If* you can grit your teeth and hold out a bit longer, it will give you time to dig deeply into the lifestyle before you head out and have to learn things the hard way. Read as many posts here as you can. Watch Bob's starter videos. Watch everyone's videos that are starting out and learn from the experiences of others..... Understand that there are channels promoting this lifestyle that do not have budget money issues, so be wary of the Rose Colored Glasses effect they can have on the impression they may put out there.... Bob says, "Have a $5k emergency fund"...
I am cheating in a way, as I filed for SS at 62, so I get a check once a month I have to live within, but I *do* get that check and it is way more than many out here have to live on.... It sounds like you *will* need to be working to "get by", and that is a rabbit hole I have not gone down... but many others have.... use the search here... there are lots of ways to earn some cash.. camp hosting, seasonal crop harvests, remote cust service..
good luck... ask lots of questions, but search for answers first ...
