Many stokes for different folks .. That's why seeing many peoples ideas / budgets are important I have no doubt I can full time on 20 grand .. However I don't want to !!! Luckily ( and I know I am) have 3-4 x that amount "all in " if I want to use it so I can stay in " nicer" parks , travel more, eat out more.. It's nice to see budgets that are more like what I'm planning.
Most posts are "how little can I spend and still full time" but that's not my situation and as I've said I know many more who must spend more than they let on but don't want to get run over by others "overspending" ! ;-) in many cases it isn't how cheaply can I full time it's what will it cost to full time under less restrictive circumstances. Everybody has their own normal and that's ok ..
