I don't know about most people but I don't always feel like I'm being as effective as I can be.
That's not to say I can't get shit done. That's far from the truth (atleast I like to think so) but I don't really start reaching my peak productivity until I'm in "the Zone," as some people call it. When the perfect balance of concentration and a sufficent dose of caffiene or other substance to balance my sporadic attention. That's when the problems get solved and the sun seems to rise quicker than usual.
So I'm just wondering... What do you do to get in the zone?
