While working on a project, such as creating a database, or programming an Excel file, I make notes about the changes I'm making.
Before quitting for the day, I add a few notes on what steps should be taken next. For example, "Create a data entry form" or "Add project codes list".
This makes it easier to get up and running the next time I resume work on the project.
If you use this technique, you won't have to spend several minutes reviewing your work to figure out where you left off -- your "Next Steps" notes will jog your memory. Well, most of the time!
