Goal setting is one of the keys to success. It is effective because it deals with how the mind works. The theory behind goal setting is, tricking the mind to believe in future results.
Some of the aspects of goal setting is followed:
1) When you set a goal, you are telling your mind to do something. You are consciously giving a command to your mind. Your mind will try to figure out anything you tell it to.
2) Your mind wants to close open loops. When you tell yourself to do something that you haven't already achieved. Your mind tries to figure out how to do it.
3) If you tell yourself something long enough, your mind believes you've already done what it is you set out to do. If you tell yourself you want to be healthy. You will begin to believe you are a healthy person.
This will make you believe you are someone or something else. You will believe you are a certain way, and in order to stay congruent to the person you think you are, you will do things that, that person would do.
If you believe you are a healthy person, you will not eat fatty foods. Because a healthy person does not eat fatty foods.
4) If you ask yourself the same questions, your mind will actively seek the answer. You will have actively your minds Reticular Activation System (RAS).
Your Reticular Activation System is the filter in between your conscious mind, and everything around you in your environment.
You see that any given second, there are thousands of variables in the environment that you can concentrate on. You can concentrate on how the air smells, how the seat fells. Your ankle pains, your headache. Noises outside, and on and on and on.
Without our RAS you will go crazy, because the mind will have information overload. What you do when you set your goals is to activate your RAS. It will look for the things that will help you get your goals.
