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

My layoff made me rethink whether to stay in my field. It has been weighing on me all week. I have good customer skills and I am comfortable with spreadsheets. How did you start?

I began with informational chats, then a short online course, then a related entry-level role. It took about 3 months.

Try a small project in the new field before committing. It told me a lot about whether I would enjoy it.
