Changing careers at 12 years into a job, is it realistic? - 14 months and counting

After 12 years as a retail manager I am thinking about moving into a different field. I have read a lot of threads here and could not find my exact situation. My family is supportive but nervous. Has anyone made a similar move?

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