I've been hurt by it. I've cried over it. I've dreamed about it. I've made future goals with it. We have joyful moments together. We have a past. We have a present. Hopefully, we will have a full and prosperous future together. My boyfriend? No no. I'm talking about money.
We all have stories about money in our lives. It's a relationship. And like members of the opposite sex, if you don't really understand how it works in general, you won't know how to apply it successfully to your life. For example, the woman who doesn't realize that many men want the chase when pursuing a woman, might make the mistake of instead chasing her dream guy and squashing his attraction for her before it ever even got off the ground.
Same with money (and prosperity for that matter). If you don't understand general properties of it, you might squash your chances of attracting more of it into your life. Or you could lose what you've already got.
