Growing up, everyone always said, "Why are you always writing in a paper planner? Shouldn't you move to putting everything in your phone?" Well yes, everyone is near their tablet or phone all day, but what is that system you use crashes? It is important to have a paper planner on hand in case that happens. With so many meetings & social life plans, it is important to have both a planner that you can write in for notes & meetings.
I love my to do lists especially when I write them out because I love crossing things off with my pencil or pen. I feel like I accomplished a lot when that happens!
