A couple of months ago I, following Leo Babauta's example, began my "year without". This means that every month, I give up something near and dear to me, be it an object, habit, or tendency, and replace it with a healthier habit. At the end of the month you're free to resume the old habit, although I doubt you'll want to.
That was the plan, anyhow. My first month, in which I stopped drinking soda, was an excellent success. Now I rarely drink soda, and never crave it. August, however, was much more sloppy. As I entered college life I found that going without bread was extremely difficult, and found myself too distracted and concerned elsewhere to pay much credence to my goal to give up bread. I also ate considerably less for the first couple weeks, which meant the cravings became unbearable.
With all of this in mind, the entire journey went on a halt as I made new goals and focused my attention on my academics and fitness.
Now that I'm more comfortable in my setting, I want to start it up again, but not alone. Doing it with others, I think, will really make a difference and will ensure that everyone involved will be kept accountable for it.
First thing's first: Does anyone have any ideas for what they'd like to give up over the next year?
