Money Versus Creativity

I am having a bit of a dilemma at the moment about what I should do next year when I finish my MA. I have applied to do a teaching course, which would enable me to teach at the local college. The course is full on and full time and would not leave me any time for creative work. However, I have been doing some voluntary work on the creative writing access course which I have really enjoyed. The second option is that I could apply for a job at the art school library. The job is eighteen hours per week and would leave me plenty of time for writing and would also enable me to apply for the Cafe Writers Norfolk Commission which I was runner up for last year. This is the only year that I have the chance to apply for it again and if I was lucky enough to win I would get a published book so it is a great opportunity...you see the dilemma - I guess comes down to money versus creativity. There is, of course, no guarantee that I would get offered a job at City College once I had trained and ideally I would like to teach Creative Writing if I teach at all and they are steering me more towards art, and there is no guarantee that I would get the job at the Art School either - maybe i should just apply for it and see what happens!
