I've started a Couch to 5K program for myself in efforts to get back in shape and to (for the love of god) stick with something long enough to lose some weight. I'm only two weeks in, but so far it seems to motivate me, and the interval aspect of it makes the 30-ish minutes go by fairly quickly. Add the fact in that I have a treadmill, which rules out weather deterring me from running, and I think I have a high chance of seeing this one until the end.
Work has been so stressful lately that all I want to go is go home, run, take a nice long shower, eat dinner, and then knit while watching tv until I pass out. This is not a bad way to spend my evenings.
