Actually going in and fixing my financials. I wasn't great with credit when I was younger, and now that I'm thinking about things like homeownership, it almost seemed insurmountable. But, once I committed that first vital step of actually, y'know, facing the problem instead of just having it as a cloud over me, I've been able to make great strides and better my living situation. I'll own my very first home sometime within the next year, if it all goes to plan!
Other than that, I've spent the last 8 months or so in a concerted effort to eat better and take more care of my body. I feel great, and more confident than ever. Yeah, it sucks when I say no to a late night pizza or another round of beer, but I feel good, and it's totally worth it. Down about 20-25 pounds, and clothes aren't really fitting well anymore - in a good way!
