The following write up on Affirmations is from a great guy called Remez Sasson at SuccessConsciousness.com I strongly recommened the site to everyone who seeks a more fulfilling life.

Affirmations are positive sentences that describe a desired situation, and which are repeated many times, in order to impress the subconscious mind and trigger it into positive action. In order to ensure the effectiveness of the affirmations, they have to be repeated with attention, conviction, interest and desire.

Imagine that you are swimming with your friends in a swimming pool. They swim fifteen rounds, something you have never done before. As you desire the respect of your friends, you want to show them that you can make it too. You start swimming, and at the same time keep repeating in your mind: "I can do it, I can do it...". You keep thinking and believing that you are going to complete the fifteen rounds. What are you actually doing? You are repeating positive affirmations.

More than often, people repeat in their minds negative sentences and statements concerning the situations and events in their lives, and consequently bring upon themselves undesirable situations. Such sentences and statements work both ways, to build or destroy. It is the way we use them that determines whether they are going to bring good or harmful results.

Affirmations work in the same manner as creative visualization. The repeated words build mental images and scenes in the mind, and help to focus on the aim, object or situation one wants to achieve or create. Frequent repetitions affect the subconscious mind, which in turn reshapes and affects the way one thinks, acts and behaves.

The conscious mind, the mind you think with, starts this process, and then the subconscious mind takes charge. This means that the most frequent thoughts that pass through your mind, ultimately affect your life and your destiny.

Affirmations work like commands that are given to a computer. They influence us, other people, events and circumstances. It might seem strange to you, but they do also influence the people we meet, our circumstances and the events we encounter.

Sometimes they work fast, but more often they need time. Repeating positive affirmations a few minutes, and then thinking negatively, neutralizes the effects of the positive words. You have to refuse negative thoughts, otherwise you will not attain positive results.

We mentally repeat negative statements, without even being aware of the process. We use them when we tell ourselves that we cannot do something, that we are too lazy, or when we believe we are going to fail. The subconscious mind always accepts and follows what we tell it, whether it is good or bad for us, so why not choose only positive statements?



How to Repeat Affirmations
It is advisable to repeat affirmations that are not too long, as they are easier to remember. You can repeat them anytime your mind is not engaged in something in particular, such as while traveling in a bus or a train, waiting in line, walking etc, but do not affirm while driving or crossing a street. You may also repeat them in special sessions of about ten minutes each, several times a day.

There should be no physical, emotional or mental tension while repeating them. The stronger the concentration, the more faith you have in what you are doing, the more feelings you put into the act, the stronger and faster will be the results.

It is very important to choose only positive affirmations. If for example you desire to lose weight, do not say, "I am not fat, I am losing weight." By saying this sentence you are repeating to your subconscious mind that you are fat. The word "losing" also evokes negative images. It is better to say, "My body has an athletic form, and weighs the right and healthy weight". Such words evoke positive images in the mind.

It is important to affirm in the present tense, not the future tense. Saying: "I will be rich", means that you intend to be rich one day, in the indefinite future. You are actually telling yourself that some day you will be rich, never now. It is better and more effective to say, and also feel, "I am rich now", and the subconscious mind will work overtime to make this happen now, in the present.

As to results, sometimes they may come fast, and at other times might take more time to manifest. Getting results depends on how much time, energy, faith and feelings you invest in repeating your affirmations, on the strength of your desire and on how big or small is your goal.

By using the power of affirmations you state what you want to be true in your life. You see reality, as you want it to be. For a while, you ignore your current circumstances and your doubts, and concentrate on a different reality.
