The only thing in the past year (going back to 2012) I would classify as wasteful spending is $90 a month for a smartphone and plan through Sprint. I got rid of that in August and went to one of the simple phones where you just re-up on minutes. I'm going to get an unlocked GSM/GMA phone from Amazon and go on their $45 a month plan -- you can even get an iPhone 5 on it, but it costs like $600 bucks -- which is way too much for a phone.
Eating out once or twice a week was also wasteful -- would spend $50 a week going out to eat when that is good groceries for me for two weeks as a single guy.
Other than that, not much. I spend little, save a lot.
