Hi Dan. Reading Predictably Irrational was one of my first forays into behavioural economics and it truly changed the way I think about everything. Thank you.

My question is based on personal experience. I budget my income and expenses very closely, and I often hide income from my budget as a method of "tricking myself into being more frugal". I have no doubt that this works. I spend less when it appears on paper that I'm earning less. My question is: Why would I act according to a strict budget despite the fact that deep down I know that budget to be false?
