Changing careers at 12 years into a job, is it realistic? - what worked for you?

I want to move from IT help-desk technician to something with more stability. I have a little time and a small budget for training. How did you start?

Try a small project in the new field before committing. It told me a lot about whether I would enjoy it.

Thanks for writing this out. I went through something close to it 10 months ago, and it settled down once I kept a simple log of every call and form.
