Short stories: it doesn't have to be a 'eureka' moment or some amazing insight, it can be something that is fairly obvious and/or not all that interesting really, or relatively random, provided it is concealed for a while from the reader while surviving/improving long term survival is going on.

Replaced a ton of my running with an elliptical trainer for two weeks now. Really seem to be getting faster. Ran 3 miles yesterday in 7:19 pace including a 6:59 final mile which is a first. Just running 3 miles twice a week for the last two and half weeks now. Paces: 7:41, 7:28, (in snow 8:05), 7:31 (ab cramp), (added ab work) 7:19. Knee still bothering me though. Otherwise feeling good. Feel like I might get a lot faster. Weight is 214.
