Changing careers at 15 years into a job, is it realistic?

My layoff made me rethink whether to stay in my field. This is my first time dealing with any of this. I have good customer skills and I am comfortable with spreadsheets. How did you start?

You likely have more transferable skills than you think. Write down what you did, not what the job title said.

Keep everything in writing and save the confirmation numbers. It saved me later.
