Tynan, I've got to say the one post that impacted me above all others is http://tynan.com/bethetwin
I'm not sure why it did, but for whatever reason, it was the biggest motivator that got me over the productivity hump in coding.
I.e. you know when you're tackling your first programming language and the simple stuff can throw you for a loop for hours? Like forgetting a semicolon and deciphering the error message, or hitting your first infinite loop and having the whole computer crash... But once you make it past a certain point you feel like you can actually build amazing things.
Something about visualizing that creepy guy in the picture, dressed up in a suit in the dog park stuck in my mind, and every time I'd momentarily try to quit in frustration, the absurd (re: unforgettable) visual images of that guy mingling with a CEO on the golf course or out taking dog sweater pictures would snap me back. After all, I didn't want that guy beating me to it or getting the supermodel girlfriend.
Now, thanks to me gutting it through and becoming an innovative programmer, I am living the entrepreneurial/daring/unique/self-employed lifestyle you very much espouse in all your writing, which if I recall correctly, is one of your main goals for this blog. If I hadn't sat down and gutted it out then, I likely never would have, as I was a student and it was the last chunk of time with which I had nothing scheduled (and thus could concentrate on a specific skill).
Speaking of which, I'm really interested in having a SETT blog now that I'm entrepreneuring full time; I know you mentioned something about signing up for a waiting list, but I couldn't find it. I'm holding off starting writing until it becomes available (I'm not in a rush, I just think SETT's release will coincide with me having enough stuff to write about regularly), so where can I sign up?
