A few points that hopefully help, some have already been mentioned -- so take the reiteration as reinforcement to their importance. 1) Exercise. I can't stress how much it helps to get a nice workout in 5 times/week and how much more energy you have throughout. 2) Get a sitting/standing desk. After I'm in the office all day, I don't want to sit. I got one myself one of these: geekdesk.com and find a more constant energy level after I get home, and I only use the sitting positions maybe 10% of the time. 3) Turn off wifi or install a "site blocker" for time-wasters. I know this sounds silly, but after a long day of work, twitter, FB, and HN all sound OOHHH so pleasant to check, refresh, rinse, repeat. After an hour has passed, an hour has been wasted. 4) Stop sending yourself articles. I did the same, but it ends up just piling up. Put everything you do and read into manageable tasks that take <1 hour and you'll be good. 5) Google seinfeld's productivity method. Another one of those "silly but it works" things.
