How we organize our personal information ecosystems impacts our productivity. Some patterns work better than others. (I’m always looking for ways of being more productive, which is why I started a podcast on this subject.) Although everyone does this a bit differently, not everyone gets the same results. I’m especially keen in finding out how very successful people organize themselves.

Few people have been as successful in the tech world as Marc Andreessen. He’s the co-founder of several influential companies, including Netscape — which helped usher the web revolution — and Andreessen Horowitz, one of the leading investment firms in Silicon Valley. Mr. Andreessen published a blog post twelve years ago that lays out his productivity principles. Given how successful he’s been, this post is worth studying.

Mr. Andreessen’s advice includes some counter-intuitive ideas. For example, he suggests not keeping a schedule. By this, he means not committing to appointments in advance. Instead, he proposes you focus your attention on whatever is most important or interesting at any given time. While he acknowledges that this may not work for everyone, it’s an intriguing notion. I live by my calendar, and this post has me wondering what it’d be like to just go with the flow. (My work doesn’t give me much leeway here. But it begs the question: what would I need to change to allow me to eschew my schedule?)

I also love the idea of managing just three to-do lists. (Mr. Andreessen suggests a Todo List, a Watch List, and a Later List.) I follow my own take on David Allen’s “Getting Things Done” approach, which means I have per-project lists; that’s too many at any given time. So I’m drawn to this idea of boiling it down to three. Also, he suggests writing down the 3-5 most important things you must do every day to keep your priorities straight. This is something I’ve been doing for a long time, to great results.

However, my favorite of Mr. Andreessen’s nuggets of advice is this: Only agree to new commitments when both your head and your heart say yes. I’ve been guilty of taking on too many things because I’m excited by the possibilities or interested in the subject (the heart saying “yes!”), only to find out later that I’m overcommitted and en route to disappointing myself and others. Giving the head a veto would’ve solved many difficulties for me.

It’s not a long post, and it’s aged well. (Just replace “iPod” with “iPhone”.) Well worth your attention.
