An idea must be brought outside the mind to have a chance – just a chance – to be of any use at all. Locked inside your mind an idea may as well not exist.

To bring an idea out of your brain it must be transformed. It can be transformed by being recorded or executed. Executed by following the instruction of the idea. Recorded by writing it, speaking it to others, or otherwise changing it to instruction for others.

Ideas are useless unless transformed.
