I agree, it sounds like keeping records and putting them in an excel, google doc or similar is probably your best bet. I have certain things I need to follow up on with work. Once I slipped up and forgot to do so. From then on, I have made note of each case in a spreadsheet and once a week I open it and do the follow ups I need. I then put updates in the task management system my client uses. It has helped me avoid problems.
