Yes! Mine is as unfancy as it gets, it's whatever pen is closest to hand and a Pukka Pad A5 squared notebook. I've been doing it since mid-September and have found it really does make a difference to how much I get done.
Mine has:
Double-page spread future log covering the next 6 months (will re-do this each quarter, adding the next 3 months, so the first one is October to March inclusive, the one I'll add next week will be January to June)
At the start of each month I have a double-page spread with the days numbered down the left-hand side for appointments and birthdays and a list of things I want to get done during the month on the right.
On the page following that each month I have a habit tracker, which has the days numbered out again and then things I'm trying to get into the habit of doing or want to track how may times I do them each month. Every time I do them, I fill in a square. It's things like 'Drink 4 pints of water', 'Spend 5 minutes tidying up', 'Yoga or bodyweight exercises'.
Other things I have pages for are business mileage, things I need to remember to do when I'm next in town (52 mile round trip, so it's annoying if you forget something!), books I've read (keep meaning to start one for books I want to read/things I want to watch), what the horses weigh on their weight tape measurements, what jobs are due back when for clients, things that I needed to get done before we went on holiday etc. etc. etc.
