I had a dilemma before whether to work or continue my studies. I was in the UK at that time and working part-time, I was earning enough so I did not really bother about college. Until I realized that everyone goes to college then after a years they graduated whilst me still working. They got work and earning more than me. That's when I realized that the level of education still is important when you want a job. I came back to my home country and went back to college.I just graduated with a degree of Nursing. Right at this moment, I can have a job if not as a nurse I still can work anywhere, for now I am aiming to work in an airline company as frontline while waiting for the board exam result.
My point is, you decide what you think is best for you. If you are aiming for a change and want to work in a position higher to what you do at the moment then go back to school. May take time but it's all worth it. Good luck!
