What to do stay and get experience or go back to collegeor w

Hi at the moment work for a toolmaking design fir. Pay aint great but plenty of variety. I am looking to either go to another similar post with a senior designer as I am out of college a year and a bit. I am seriously think also of going to a design college in the Uk as I seriously love doing art and it would allow me to combine art and engineering possibly.
… I want to do some travelling to…

Any words of wisdom or advice from all the worldly people.

If you want to get into design, I’d go back to school as soon as I could.
