Planner

I will say most of the time I do, i carry my planner at least the whole week, but not on the weekends...

I seldom use a planner though sometimes I do. I think that it is good to always use a planner as a reminder to us for fear that we should forget. Sometimes I do forget what I should do as I don't use a planner.

I still use the old traditional planner and write important stuff there such as birthdays, things needed to be done, holidays, telephone numbers, important informations, reminders, etc. I find it so handy and it is not really big in size. I use it everyday. Though I also use my mobile phone and store also these things there. But I find my traditional planner to be more useful for me.
