For lack of something better, I settled on excessive internet use as my repetitive action. I check my email anywhere from once to five times a day. Before a kindly neighbor chose not to secure his wireless, my access to the web was limited. I checked it once or twice daily at school. In comparison to last year, my habit seems to have grown out of control, but I speculate that if the number of times I check my email was compared to the number of times the average student checks his Facebook account (I have avoided getting one thus far) I'd be a beacon of healthy restraint. Five checks per day is nothing in our modern technological era.
Ultimately, I have no need to axe my annoying habits - what I need to do is start more healthy ones! For example, why not finally make use of the calendars my Mom gets me every year? I could benefit from a little organization in my life. Why not take yoga and work on stretching my freakishly inflexible hammies? Why not set goals for how much writing I do every week, how much music I play?
It's easy to get worked up with this kind of attitude. Every New Years, millions of ambitious resolutions are made that have no forward momentum. It's easy to say you'll change. I guess the question we have to consider is whether or not it's easier to quit negative behavior, or maintain positive behavior.
