Should I go back to school?

I stopped going to college about 4 years ago due to financial reasons. I stopped when I was a 2nd year standing and since then I just started working while my sister continued studying shortly afterwards. She's graduating next year and everyone's been asking me if I wouldn't want to pursue my course. While my sister was busy studying and working at the same time, I've been traveling around the world joining tours, dating socials, events, concerts and more. I love the life I'm living now but I can't help but wonder if I really should finish and get a degree now that I have the money to continue. What should I do? I'm torn between the life I'm enjoying now and going back to school and spend my days cramming. Any advice?
