Changing careers at 11 years into a job, is it realistic? - any advice?

I want to move from warehouse supervisor to something with more stability. This is my first time dealing with any of this. I have a little time and a small budget for training. Did you take a pay cut?

Thanks for writing this out. I went through something close to it 6 months ago, and it got easier once I kept a simple log of every call and form.
