I am thinking about trying to make a career change but everyone says I am crazy to try to do it during an economically difficult time. (I have to go to school for a couple of years to do this.) I had some momentum but now I'm starting to get stuck in fear -- what if it doesn't work? What if I can't get a job? Would I be better staying in my job now and being grateful for the pay I do get? I'm just wondering how people have made this kind of decision in the past? How do you know you're doing the right thing?
