Cupcake15- I also keep track of the miles that I jog. This keeps me motivated because I have a weekly goal. I also include my finishing time and look back month after month to see how much progress I have made.
A personal day planner is great for goal setting because you can look at your goals daily and even break them down smaller in to more manageable steps in order to be successful.
My kids even use a day planner at school because they are trying to teach them to write things down and become more organized with their school work and assignments. This makes it easier for the children to remember to do their homework.
You really have to consider the cost when buying day planner organizers. Some of them can be expensive, but sometimes you can get smaller desk day planner a little cheaper.
