being disorganised, and making bad food choices when hungry, is what got me and many others no doubt where we were weight wise... when hungry, I'm fair game if tempted!
When working full time (and living in two residences over the week), I've no choice BUT to be organised... and when people say they don't have time for this or that, I'm often tempted to say that "we all have the same 24H, just that we choose what we do with them". I'm a good multi tasker too and, if the oven's on, I'll fill it and freeze... if I'm standing at the stove for one thing, might as well do two, then package into individual portions and freeze.
