I agree with Wifezilla. Couponing is just a drop in the bucket. If you follow Dave's advice, he will teach you how to manage your money, rather than letting your emotions and money manage you. Once you have those basics, then you can start fine-tuning.
It sounds like you have a great dream and just need to establish the steps necessary to get there. Clarify your goals by writing down exactly what you want to accomplish and breaking that down step by step. Keep those goals in writing in your wallet, beside your computer monitor, where ever you are when you spend money. When you are tempted to spend, look at those goals and ask yourself if that purchase takes you closer or further away from your dream.
And don't kid yourself that it will be easy or that there are shortcuts. It's not and there aren't. But it will change your life and be worth it!
