A common reason for procrastination is a lack of connection between the to-do list and the calendar. To move forward, Make Time on Your Calendar for Tasks.
If you have a task that takes 30 to 60 minutes (or more) to accomplish, it belongs on your calendar, not just your to-do list. To-do lists are intentions. Calendars reflect commitments. It helps to visually see that the “free” time on your calendar is actually allocated for work. And if you don’t designate the time for lengthy tasks, they’ll keep getting ignored until they are due or forgotten.
