I love this. I am constantly trying to tweak my day to yield maximum possible productivity. Between four kids, an epic daily commute, and the demands of a logistically intense job, it's essential that I keep on top of things.
I've tried "winging it." It doesn't work.
I recently started using Evernote, and while it's not the ultimate productivity enhancer, it's part of my essential toolkit.
Anyway, check this out. At first glance it's amusing, but then you realize one of the greatest minds in history structured his day. While individual structures will vary, it's still neat to see how he did it.
