Why don't you use this time to visualise a job/career that you would LOVE to do forever, something that wouldn't really be like work. (Dig the shopping idea tho!)
Really work it - shoot for the stars and all that! I have a rather high-pressure, sad sort of gov job that I only stay at for the money. I used to be able to really help people but not anymore.

I decided on MAT leave that I wanted -
part time or flexible hours,
good pay,security
no stupid, boring offices
recognition for work well done,
something to look forward to,
be able to go on lots of holidays

Idealistic, maybe, but realistic for me now - I held out for what I wanted and now I'm awake every morning at 6am, getting work done on the pc when it's quiet (very unusual for me!!), I love it and I wish I'd done it earlier.
My dad is 80 this year and he is still working. He is a psychologist and loves it so much he would miss it, and it keeps his brain razor sharp. He still says he can't believe he is paid for doing what he loves.

Lifes too short to be doing something you hate! Live the dream baby!
