I can totally relate. I am in the same position. I left working at a coffee shop to go to school, and now that school is done I have been searching job postings and I am not remotely interested in any of them. So I reapplied to work at the coffee shop. I was worried about what friends and family would say about how I am not using my schooling and whatever, but I don’t have any inkling of what I want to do. And in the mean time I would like to work in a fun environment where I get some benefits and perks.
I don’t think it’s going backwards. it’s realizing that you actually liked that job, and had found something that you were good at. people try for most of their lives to find something that they like to do, and that they are good at, you are just ahead of the game.
