"I can't remember anything any more," said one of my clients. "None of us can," I told her. And it's true. And that's why lists are so helpful.
Here are some of lists I personally find useful; I'm sure you'll have others of your own.
So where do you keep your lists? If you prefer computer-based options, you can use simple text files or spreadsheets; there are also many programs designed specifically for tracking such things. If you prefer paper and pen, there's a huge range of notepads, notebooks, and journals. And some people find a white board is the perfect answer.
So pick your approach and give your memory a break; get those lists out of your head!
