Major life progress from November:
1) I feel like I've brought my social media addiction under control. I might still spend the whole day on Facebook, but now it's mostly because I choose to: I haven't lost a day to the site against my will for a while anymore.
I achieved this by following the advice in _The Power of Habit_ and changed my routine while keeping the reward same. Namely, whenever I get an urge to go on FB when I shouldn't, I check my notifications via the slow GPRS/Edge connection in my phone. The slowness combined with the tedium of typing on a phone keyboard makes the experience much less rewarding, and easier to pull out of. (I just hope that I won't be forced to upgrade to a real smartphone at some point.)
2) Shifted my diet in a much more vegan direction by finally eliminating the cheese pizzas from it and generally making an effort to stop buying foodstuffs containing animal products. I thought this would be considerably harder, but it turns out that the shift from a meat-eater to mostly vegetarian was MUCH more difficult than the shift from mostly vegetarian to mostly vegan, at least for me.
As in Joshua Blaine's original description (below), but may be used to brag about things you've accomplished either this month (December) or the previous one (November), assuming that you haven't brought it up in any earlier Monthly Bragging Thread.
