Yeah, you're totally right about re-reading. It helps a ton. That's actually what I did today. Still, it's always more enjoyable to read something new.
One problem is that I've re-read (and re-listened) to everything PG and Pmarca have ever posted on the damn internet, many times over. Now I just re-read the best ones for the 20th time. I read/listen on the train, at lunch, and at the park so my appetite is insatiable. Need. More. Content.
