"This planner is exactly what I needed to keep track of everything. I love the timeline and stickers so I can mark important "to-do" dates and stay organized. It fits in my purse so I can keep it with me at all times! It's kind of cheesy with really sappy quotes on each page but it doesn't detract from the functionality so it doesn't bother me."
