Went back to school and finished my degree at 39

I'm officially a college graduate as of last month. Took me 15 years to finish what I started at 24 but I'm done. Had my kids during the last three years of it which was absolutely brutal, staying up till midnight doing assignments after work and bedtime routines. But man it changed something in me. Not just the degree itself but the fact that I proved I could do hard things. My kids saw me struggling and pushing through and I think that matters more than the diploma. The weird part is I miss it already, like I actually enjoyed learning and now I don't have that structure anymore.
