Changing careers at 13 years into a job, is it realistic?, electrician's helper here

After 13 years as an electrician's helper I am thinking about moving into a different field. I have been trying to stay organised about it. 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.
