If I understand it correctly, much of the power in Beeminder comes from the threat of losing money when you fail. How many times did you fail at writing before giving up? I have not used BM in a while, but I did successfully use it for writing.
(Number of consecutive push-ups doesn't seem like a good thing to Beemind. If your body doesn't have 50 push-ups in it, wanting it really bad isn't going to help much. Tracking number of push-ups done in a given amount of time would probably work better, which would naturally increase consecutive pushups.)
I very much agree with the parenthetical about pushups. I beemind 30 pushups per day -- http://beeminder.com/d/push -- with the idea that I'll gradually ramp that up as my max reps increases. Except I'm failing to ever do that and have been at 30/day forever. If I cared more I'd ramp it up though. Right now I'm just happy to be forced to maintain some semblance of baseline upper-body strength.
The general point: beemind inputs, not outputs. Ie, things you have total control over.
PS: The Beeminder android app has a pushup counter built in, where you put your phone on the floor and touch your nose to it on each pushup and it tallies them for you.
