Simply put, the Law of Attraction means that "like attracts like."
Psychologically, it means that whatever you focus on, think about, believe, or otherwise give your attention to, is amplified and perpetuated in your experience.
For example, if you believe toddlers and teens are naturally rebellious, you'll notice their antisocial behavior more than other behavior. And since kids like to be noticed, they'll give you more of whatever behavior you're noticing. Resisting such behavior only makes it worse by keeping you focused on it.
The good news is that it works both ways. So if you find a way to soften resistance and deliberately appreciate your children, yourself, and your life — as they are — then you’ll attract the kind of experiences you really want.
