Thought of the Day - Ideal Job

I don't think i know what my perfect job is and if i do (or at least have an inkling) then i have no idea how to get there. At the moment i am just bouncing around from job to job doing things that seem interesting. Which could be worse; i make decent money, i learn new stuff, but despite the fact that ~90% of my life is work i don't really feel fulfilled. Is it because i need more of a balance (find a hobby other than getting new jobs) or is it because i haven't found the right job yet?

If my ideal job doesn't exist can i create it? I really need to refer back to an earlier post about working out what problems i am uniquely able to tackle based on my strengths and try to think of a job that fits with that.
