Honestly, any life planner will probably do, but my planner of choice is the Erin Condren Life Planner, which I will never stop gushing about. I have NEVER found an electronic calendar that I've actually followed, so I need to have something tangible to look at. And yes, I track pretty much everything on it: bills, work deadlines, habits, time-of-the-month, etc.
Writing things down helps me commit things to memory better, and decorating does, too (plus, it's fun!). I've found that there have been certain events that I needed to recall by memory, and I was able to do so because I would remember "Oh! This happened during the week I decorated with a Frozen theme. I remember it happened on Friday because that's where I put the Elsa sticker!" Nerdy? Yes. But I love it, and it helps me (and trust me, I basically have the memory of a goldfish, so this has made a huge difference in my life).
Plus, I love the layout of the EC, and how high quality it is. I got the chance to meet Erin Condren and hear her speak at a convention earlier this year, and I really loved her, so I'm more than happy to continue supporting her business by buying her products - I feel the planners are well worth the $55+ price tag, since I use them daily. If the price is a bit high for you, however, there are some decent planners available at Target.
A couple other planners that I've tried out and like are the KitLife Planner and the Day Designer. I recommend that you research which planner and layout works best for you (there are a TON of helpful reviews to be found through Google), as I know that everyone's planning style is different.
- update which page you're on (very useful if you're reading a long library book & have to return it before you can finish because it's on hold)
- save your favorite quotes by either 'liking' them or adding them to the database
- find out what your friends are reading
- get curated recommendations based on your previous ratings of books (their recommendation system is the best I've ever seen - I constantly find amazing books through it)
