Yeah. There's an excitement to creating a budget, the prospect of financial independence from high-interest debt. A honeymoon period if you will. It fades fast and the reality of adhering to it will hit hard. For some people it's a couple of weeks later, for some it's a few months. It almost always hits though.

Knowing it's in the budget makes it a choice not of whether to follow the budget, but how best to allocate that part of the budget.
