I disagree with the $100/hr thing, I'd go with $40/hr or so, but with 6 months living + 40 buyins backed up. Sauce makes a good point about fatigue.. maybe my figures are a bit off though, I live in a very cheap area and can get everything (survival, not beer and cool stuff) covered in a houseshare situation for $700/month.

Oh, and comparing poker to most jobs in terms of the hours you can/should put in is bollocks for most jobs IMO - working in a social setting where you know that you could work harder but don't give a fuck because the workload isn't bad (which is about 80% of jobs I guess) is 10x less tiring than pushing yourself alone because you have no-one to answer to.
