Many have misunderstood the way The Law of Attraction is meant to be used. It truly doesn't matter what kind of a life you have lived, if you have done good things or bad things, The Law of Attraction is responding to your vibrations now.
Now many will keep themselves from getting want they want in life because they themselves believe they are unworthy. The idea that you have to work hard to get ahead, or that you must have a good education to be worthy of the things you want in life is a false premise. All you have to do is match the feeling place of what you want and The Law of Attraction will and must deliver.
When you are thinking of having a better relationship, or a new job, more money, or better health you are always transmitting a vibration. Now as long as you focus on what you want from the place of how good it will feel to have it, instead of, how bad it feels now not having it, you are sending out a signal to all of the Universe that says "I am a vibrational match to what I want" and The Law of Attraction goes to work.
Most people however do the exact opposite. They focus instead on how they don't have a good relationship, on how much they hate their current job, don't have enough money, and how they are always feeling bad and that vibration is going out and being answered by Law of Attraction instead.
You see, Law of Attraction is impersonal, it does not care about anything other than your vibrations now. It is a manager of vibration and must match you with people, places, and events that match what you are emitting.
When you want something and are looking forward to having it from a place of excitement, Law of Attraction goes to work. When you want something and don't believe you can have it and are looking at it in doubt and fear and from a place of discouragement, Law of Attraction goes to work.
Whether you really want it or you really don't want it, all Law of Attraction sees is that your attention is on a subject and you are very excited about it and it goes to work to bring it to you.
Pay attention to how you feel and you can steer yourself in the direction of what you want more of the time.
