It might be just age, but I now need to start each workday composing a task list. Not long ago I could multi-task with the best of them; bouncing from client facing tasks to production meetings and interviewing designers. Now we have scribbles on a pad with little asterisks next to each item. As I do it I highlight the asterisk with a marker; when it is completed I highlight the item. It wouldn't be surprising to soon hear me frequently say, "Can I biggie-size that combo?"
