A while ago I wrote that a good idea becomes great when it is severed from the heart. I'll elaborate on that briefly.
Memory is a defense mechanism. Experiences are abstracted in the memory in order that you may repeat the good and avoid the bad. These abstractions are often very complicated and difficult to distinguish from their source. If you want to work autonomously in the abstract space (probably impossible given it's a byproduct of this defensive system) you must learn to recognize these "instinctive" [reactive] abstractions and ignore them. A truly great idea transcends the mind that thinks it.
