Unfortunately, at this point, just for getting by. House, Food, Utilities,etc. For years I would say i have been severely underspending so when I make more money I more or less just add "normal" expenses that others take for granted until i reach the boring normal expected lifestyle.
I'll put it this way: We all know people who work their asses off for other people as employees at a job only to barely get the bills paid. Well. for me its like that except I don't punch the clock for anyone except myself and i prefer it that way.
The good news is that I make real progress with my business every day and that i know if this point is the worst it will ever be it's alright. Even if something catastrophic happened to my business i would easily be able to meet my needs and never have to worry about the whims of others affecting my life.
Like some others, I pretty much invest everything ( and then some) back into the business, in acquiring more websites, improving my ROI on existing properties,etc.
So the one thing I probably spend my money on is websites/domains, tools,etc. I dont really count that because its not a personal expense.
As my income grows it will probably go into making my house more enjoyable, maybe buying some more, and eating out.
