going home at the end of the day wondering what I'd achieved Keep a log throughout the day. It helps. Failing that, use email, issue trackers, repos, purchase orders, inventory logs or other major communications channels / process interfaces to retroactively summarize progress. I currently do this weekly, and use it as input to reporting and planning processes.
