Don't forget Nothin

The question in the LinkedIn group Leadership Think Tank was: "What do you believe to be the top three (or more) "secrets" of your success?..."

My answer is:
"Don't forget nothin." - a poor rendition of Robert Rogers' 28 "Rules of Ranging"
together with...
"Don't memorize anything..." - Attributed to Einstein

To me this means:
Pay attention to everything.
Determine the first principles involved.
Incorporate these into your knowledge base.

This way, you don't have to memorize facts. You internalize a few key principles. With these you can access the details whenever necessary and also be able to do much more then repetition alone allows.
