Here is a common excuse for not organizing a budget, and why you should make one anyway.

Excuse 5: Budgets are meaningless. Everyone just fudges the numbers to paint a pretty picture of how things ought to look. Creating a budget that is based on too-lofty goals, hoping it will provide the inspiration to achieve them, is a sure-fire way to set yourself up for failure and frustration. One internet post compared budgets to pornography: "a fantasy about how the author would like the world to look, having no relation to the realities of the world, designed to titillate, stimulate and motivate the reader, but ultimately resulting in a sense of alienation and despair." Long-term, that’s of no use. When it comes to budgets, you can and should keep it real.
