If you don't have 'sense of time' you should better use Calendar (instead of To Do List)

Do you manage your time?

If you are constantly rushing, always being late for appointments and very often missing deadlines, you just don't manage your time or you manage it the wrong way. We all have the same 24 hours a day, however, some of us manage to do everything they planned while others handle a few tasks no matter how active they are. The difference between these two groups is in 'sense of time'. Some people just can not measure the time and think that they have plenty of it for all the tasks they have.

Use calendar

The solution for this kind of people is calendar. If they can estimate the right time for each task it is much easer to schedule them on calendar. Calendar grid in comparison with To Do List shows you that time is not unlimited. You can not fill in '30 minutes' cell with a task that takes 1 hour to complete. Finally you will have a time grid with less tasks, but these tasks will be more essential. As you will have to refuse from some tasks, you will need to set priorities. According to Pareto principle, focusing on important tasks will only help. :-)
