I read something a long time ago about optimization that really stuck with me. I don't remember the source or the exact words, but the gist of it was, "The only way to make a program run faster is to make it do less. Any other plan is just that." The same goes for humans. The army also has a saying, "Haste makes waste." Doing the same things we do now, but faster, will only create problems. There are many different plans for becoming more productive out there, and I'm not saying they aren't effective, but they won't be tailored to your needs. You're better off looking at what you do and finding the things you do that aren't productive, and cutting those out. Any other plan is just a watered-down version of that.
