asking your advice

How much time I need to spend commuting is a pretty big factor in my salary requirements. It's worse now that I don't have a car (on good days yes, I can read on the bus or even draw, but on bad days I have an hour of being crowded, inactive and cranky). I'm really desperate for work, and I know I want to jump at anything out there, but the last two times I jumped at a temp job because I felt I really needed the work, it was crummy for my emotional state.

I'd like to ask for help from anyone reading, about matching salary requirements to transit times.

For reference, I live a short bus ride from the Oakland BART station, getting a bus to BART and a BART ticket is about $4 each way, $10 is the minimum wage in San Francisco proper, and I mostly work doing data entry or administrative assistant jobs which are somewhere in the $12-20 range (depending on how sleazy the hiring manager is).

Here's what I've been vaguely thinking of as guidelines;

$10-14/h for a relatively short commute, perhaps under 1 hour, for instance within Oakland or to parts of Berkeley which are easy to reach through BART.

$14-18/h for a fairly standard commute, maybe around 1 hour or more, for instance to the Financial District or deeper into San Francisco. Where I'm not sure this really works is for jobs which are around 2 hours or so each way - for instance, bus/BART accessible parts of let's say Concord, Fremont or South San Francisco.

The thing which got me thinking about this was an $18/h job in Foster City (2+ hours away each direction) which my gut feeling is a no.

Would you have any opinions about this stuff?
