Of the many I have, shopping wisely is very high up on my list. I regret how much time I wasted obsessing. I understand taking time to think about a purchase, but spending hours thinking about whether or not to get a particular item is not healthy. There's too much life to be lived and work to be done. Took me a year but I think I have finally learned patience and self-control. I made it three months without shopping, and the Earth is still spinning :) Hope to keep this up, not just in 2012 but from now on.
