If I pull once, I consider the day a loss and don't really try for the rest of the day. I'm also kinda ocd about starting things. I like to start things on Sundays (I'm sometimes okay with Mondays- since that's the beginning of a work week) or on the first of the month. If I'm going to start exercising, dieting... or trying to be pull free it has be at the beginning of the week- not a Thursday. And if I fail at what I'm doing during the week... I tend to just give up until the following week starts up again. Maybe this quirk is just an excuse?!?! Something I need to work on.
