Changing careers at 3 years into a job, is it realistic?, HR coordinator here

I want to move from HR coordinator to something with more stability. I am in Knoxville, in case local advice matters. 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 12 months.
