help...

i was at a job interview at jämtteknik the other day, and of course i'm now expecting a job offer any day. but what will i say when they call? do i really want the job? one minute i think i do, the other i'm sure i don't. i'm going through lists of pros and cons in my head constantly (that's probably why i've had a head ache since tuesday morning).
good things about jämtteknik:
probably more fun tasks*
higher wages
bad things about jämtteknik:
* maybe extremely boring tasks
i won't be able to walk to work anymore
the first 6 months i will have to go all the way to ö-vik to work 2 or 3 days a week
thing about jämtteknik that i don't know if it's good or bad:
all 20 employees today are men
good things about my present work:
nice colleagues*
i can walk to work in 15 minutes, by bike it takes less than 5
bad things about my present work:
* many of the nice colleagues are leaving for other jobs
not always very much fun (not extremely boring either)

the short short version: is it worth to leave a job that is "ok", with many colleagues i like and that i can walk to (which is really the best thing of them all) for a job that i think will be more fun but that will mean i'll have to buy a car (the saab is dead and the toyota is dying) and that i will have to get up at 5 (!!!) 2-3 days every week for six months?

another question: is a hot bath good or bad for head aches?  ¶ 12:32 PM
