I think choosing the right planner is difficult. Now that I'm retired my planner plays a different role than it used to. I've played around with several different styles over the past few years but I always come back to the Happy Planner as my favorite. I like the classic size and the mini. I used the Big one year but it was really almost too big for my needs. Technically I don't "need" the mini and sometimes syncing them is a pain but I also like the smaller size to slip in my purse. Does anyone else use a Happy Planner? These are the styles I picked out for 2019.
