If you are at all interested in personal productivity, then you need to clear your calendar and read:

Pmarca Guide to Personal Productivity by Marc Andreessenn And here's why:

• I used to have a very complicated to do system that took a lot to maintain. After switching to the 3 list strategy I spent so much more time doing my to dos instead of teaching them.

• Dealing emails twice a day took me a while to stick to, but once I did my productivity went through the roof. Chances are the email you were going to reply to won’t be read until tomorrow so do it later.

• Deciding the last night what my priorities are today means I can wake up and get straight into it. I’ve eliminated the chances of being distracted by other thing when I have a clear plan. Having it in an index card staring at me is the perfect way to keep me on track.

• I’ve procrastinated for as long as I can remember, but after reading this article the time I procrastinate is productive. I get so many odd jobs done when I’m putting off the more important task it’s ridiculous. I do limit myself to 30 minutes though so the important tasks still get done.

• Writing down and being able to tick off things on the Anti to do list is a dopamine hit. It’s amazing how many things you forget you have done in a day

Honestly, this blog post changed my life—and completely changed the way I think about productivity.

I can't believe stuff like this is free on the Internet.
