The methodology for establishing the concept.
Use either a blackboard or a pad of paper and throw all your ideas out on to "the table". This method of expressing your ideas will help you to clarify them, you may add or rule them out as you see them and they will become more clear to you. They will take on substance. You look at your ideas in the way your audience will when you express them in your speech. In the same way you clarify your goals by writing them down you will see your ideas in a more realistic light. The reason for this method of gathering and assembling your thoughts is that your mind is like a hard drive of a computer, it's contents or thoughts and ideas are stored randomly or in no particular order or sequence. There is a theory that dreams are just a method of the first stage of placing thoughts in some kind of order ready to be assembled and placed in a logical order. This method is an unscrambling of all these pieces of information and is basically used in all decision making whether by design or not. The mind uses this procedure on it's own when given time and opportunity. In most cases unless the procedure is deliberate it usually does not take place. Emotional blocks created by stress or the existence of too much information as a result the mind cannot cope with the mass and confusion results. You can liken it to a "traffic jam" of ideas.
Once we have accomplished this assembling of your ideas and thoughts we are ready to set up the order or pattern that will set the context of your speech or presentation. When using this method you must be confident. It requires a free thinking approach before you reassemble the thoughts and ideas into logical order before writing the actual presentation or speech.
