Right now I'm trying to get some credit and whatnot so I often think "I should have gotten a credit card much earlier" but I'm kinda glad I didn't, I'm sure I would have cocked it up and racked up a lot of debt.
Pretty happy with my decision to attend community college and not own a car, though. Money pits.

My issue right now is learning to sock more money away. Have a Wealthfront account that auto-deposits every month, but I'm not sure if that's enough at this point. 401k is in a good spot, though.
