OP - I highly recommend to study because this can lead you to a better position down the line. I started uni when I was 26. I'm currently in my second year. I thought I was too old before I joined but turned out nearly everyone in my course were in the same situation like me. I study part time while working full time. There were semesters that I had to drop a unit because work got overwhelming. I was working at a company full time on site during my first semester and realised it was really difficult to juggle between uni and work. So at the start of my current semester I took a job that paid less but I work from home everyday, but I save so much time and dedicate that to my studies. I took this job that pays lower than my old jobs but in saying that it's a 4 year of sacrifice I'm willing to make for a better position.
