The Law of Attraction is basically that like attracts like. If you think or act negatively, you get more negative. If, however, you think or act positively, you get more positive. It's also known as the law of sowing and reaping or the law of the harvest. You get what you deserve ultimately in this life.
One thing many people may not know about the Law of Attraction is that you don't get what you want. You get what you expect. If you want something but don't expect it to happen, the chances are smaller that it will happen. Think of how you feel when you want something. It's a yearning, a reaching, but almost an uneasy pit in your stomach. Now think of having something wonderful. What does THAT feel like? To me it feels like a peace and confidence - being content.
If you WANT something, learn how to EXPECT it. You can do this by faking it until you make it, so to speak. Think and act like you already have it. What type of person would you be and what would you do if you already had what you desire.
I know that's a simplified version of the Law of Attraction. However, if you need more help understanding or learning how to apply it into your life, remember that I offer a free consultation.
