Doofus strives to boost his energy and manage his time.
Sharpee strives to manage his energy and leverage his time.
Explanation: Have you ever noticed people on constant caffeine kicks (or are you one of them)? They are scurrying around trying to get everything on their list accomplished, yet never seem to get it all done. In fact, it seems to be an American way of life lately. Then you see people who are always just so calm, but they seem to accomplish so much more. What's the difference?
The sharp individual does not seek to artificially boost their energy but rather recognizes their natural limitations and rythyms and works within their boundaries. Instead of focusing on the process of getting lots of things done, they focus on getting high value things done and pushing low value things into the future ... or giving them to someone else ... or not doing them at all. The more important things you can handle, the more success will find its way to you.
