I have a few goals for the new year but no resolutions. I quit drinking and smoking years and decades ago, respectively, and don't have too many vices left that I have any inclination to resolve at this point. Perhaps next year I will, but not now.
Resolutions, it seems, are mostly to stop doing things... getting rid of bad habits. Well, maybe not. We can resolve to take up more constructive activities, but if it's something to do just for fun, resolving to do it might take some of the fun out of it. And at this age, if it's not fun, why do it if you don't have to?
