Congrats on paying off your student debt! That’s AMAZING! 
I think it’s so helpful to hear you mention how you’re trying to use that extra $600 intentionally. Whenever I’ve gotten a windfall or had a boost in leftover cash by paying off debt, I’d also have to be really intentional and plan out exactly how I’d spend or save that cash. Otherwise, I’d use it mindlessly. For me, I’d do a mix of saving and boosting some categories that might have felt tight. But I’d also give myself a little boost in discretionary so that I could have a little fun too.
Thanks again for sharing! I really do love reading your updates, so keep 'em coming!
P.S. I agree that doors are more exciting to think about than roofs
