I'm not super productive but much better than I used to be. I try to make good lists with a clearly defineable goal, and break as many things as possible down into 5 minute action items and give those priority when i have a few minutes. By action items, i mean actionalble things - not "think about AB" / "plan to CD" but "get prices on QRS" and "organize X by Y for Z". Also if something has a due date I put it on my google calendar and have it sms me a reminder before the thing is due, in varying intervals. I try to have nothing sitting in my email inbox. Either gets archived immediately to work / family / advertisements / craigslist labels or it goes into the todo or waiting-on folder. Schedule a review for everything at least once a week. I do get bogged down in lists, but it's not as bad as it used to be. I used to write lists on the back of reciepts and stuff them in my pockets. Now I keep them in notepad++. It's far from perfect, but I'm still working out the kinks. I need to waste less time on the internet but I end up opening a tab to read something and by the time I'm done with the article I have five new tabs open and a new todo list started. I need some software to sort all this info, still working on that. david allan's GTD
I read his book and it was pretty good. Lots of great concepts, but the way he does it requires much more paper than I'm comfortable with using. Tim Ferris has a blog entry on how to phrase emails to personal assistants
that I found useful in my list making. I don't have a personal assistant bit I have found that if I'm this clear and concise up front when writing my todo list, it helps me tremendously when I am trying to execute on a time crunch. time is valuable.
