Yeah, the thing is that, unless you actually make a plan or a list of some kind and stick to it, it's like walking into a store w/ all your money in your hands and begging the salesperson to tell you what it is that you may need...
As I said, identifying what you need and why you need it can be a good first step. Of course, there'll always be this attraction for shinny new toys, but when you have a plan, it's easier not to dilapidate your budget on just about any thing.
