Sometimes I find myself so stressed out by the standup, I basically doing nothing the rest of the day. Also I have a habit now to get up early and try to do yesterday's portion of work in an hour or two before standup just to report it. I completely stop thinking in time periods wider than sprint, and I thought before that was my strength. Worst thing, the process forces an idea that my struggle with it is, basically, my fault. I hate "scrum".
