Lifehacker posts this post from Wise Bread. I know it is complicated.

I like this tip for saving money.  I am not sure it work for me, but I would like to try. The whole put all the money in one locating thing… I guess the planning of it.  I do believe in watching costs, but… hmm.. just not the best at it all. I keep things as simple as possible.  More like I set everything up and then see what is left over for fun.  After savings and retirement of course. I don’t know, I will talk to my wife and see what she thinks about this.
