Changing careers at 4 years into a job, is it realistic?, marketing coordinator here

I want to move from marketing coordinator to something with more stability. It has been weighing on me all week. I have good customer skills and I am comfortable with spreadsheets. Did you take a pay cut?

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

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