For years, I used a Franklin Planner to plan and track daily activities because the company I worked for mandated it. In fact, they wanted employees to attend seminars on time management. After leaving the company, I started to question the cost of annual planner refills. I tried using less expensive Day Planners, but found them too small. I fell back on using online calendars such as the one included with Comcast email and Google Calendar. Finally, I came up with a system that works for me. I created a very simple Excel spreadsheet called DailyTasks.xlsx. It is formatted like this:

The days are grouped by month, with each month on a separate tab of the spreadsheet. It looks like this:

There is a tab at the bottom for each month.

This simple system eliminates a lot of stress because it's real easy to prioritize tasks in a day and put them into the order I want to do them.
