On budgets

I really need to create a budget. I'm a shopaholic, I can't deny it, and I love eating out....and I have no discipline.

Ugh...how can I motivate to actually create a budget (which in and of itself seems exhausting to me) and then actually stick to it.

My problem is that no matter what is on my budget, I'll still buy plane tickets that I can't afford ... and shoes that i can't afford ... and well...pretty much everything else that I want that I can't afford.

I'm doomed.
