Changing careers at 10 years into a job, is it realistic? - 7 months and counting

After 10 years as a procurement assistant I am thinking about moving into a different field. I worked as a procurement assistant before this. I have good customer skills and I am comfortable with spreadsheets.

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