I have always relied heavily on a planner for my scheduling and to do lists. Here are some tips:
Make your weekly goals attainable. I would love to write down that I am going to work out every day. Realistically I am happy to get in three times a week. So I will write down work out three different days. Even if it doesn't happen that specific day, I try to get those workouts in by the end of the week.
Don't overload yourself. Three or four items to cross off your list for the day plenty.
Keep your planner in your purse or readily available. When you have down-times out and about, it is a great time to jot down a few things that you are thinking about accomplishing.
I keep a list of grocery or other items that I need to purchase on a post it on the current week. Then I am ready to go to the grocery store, I can pull out that list and stick it on the shopping cart to easily see.
For me, having things written makes a huge difference. Crossing off an item makes me happy:)
This is a to do list from Johnny Cash that recently sold at auction. Some interesting things on there!
