I'm tell ya, once you live in a car, you can handle anything in life.
150-250 a month in food . . . eating ramen all the time?
i'm in a similiar boat like you, except my figures are significant higher (job & AM). still i don't feel comfortable to leave my job because i rely on too few traffic sources and profitable campaigns.
on the other it's hard to bring your AM game to another level when you're tired every evening and only spend a few hours a week.
Or because you want to become your own boss?There's nothing wrong with that. It doesnt always make sense to quit your job and choose AM, you're usually pushed into it without choice for one reason or another, the main reason being you're laid off, etc.
My savings should alow me to live a couple of years with a reasonable lifestyle. But that's not what they're for actually.Quitting a job to pursue AM is easier if you're single and can afford to fail without it affecting others. Or, if you've "banked" enough by doing AM on the side with your FT job you can afford to coast a few months.
