Changing careers at 15 years into a job, is it realistic? - first time posting

After 15 years as a delivery driver I am thinking about moving into a different field. I worked as a delivery driver before this. I have good customer skills and I am comfortable with spreadsheets. Did you take a pay cut?

I began with informational chats, then a short online course, then a related entry-level role. It took about 5 months.
