I've been following this thread since almost the beginning - had seen bullet journals mentioned a few times in various places and was sort of intrigued, but finally thanks to this thread looked at it all properly and have been converted. I had a big notebook (A4, one of the soft cover Ryman's ones, which are very good and excellent value) that I'd started using back in November, with a few different labelled lists in (holiday, Christmas, etc), plus daily to do lists, so reading about bullet journaling kind of brought it all into focus for me. The index is such an obvious thing to do once someone else has told you to do it!
Anyway, although I felt like I'd written loads of stuff in this notebook, it was only a few pages, so I carefully cut them out (couldn't start not on a first page!), and have started my bullet journal. A4 is fine because it sits on my desk - I keep a calendar on my phone to add things to whilst I'm out, or I'm at work and have a diary and notebook for there too. Planning to get bullet journaling for work too, but haven't started yet.
I've got a key on the inside cover, then an index. Realised I am definitely going to need more pages for my index! But that's ok. Then have a double page spread of the next 6 months. Then facing pages of a February calendar, and a February to do list - so CutYourHair this is where I would write down "stuff to charity shop - Monday?" - and I cross these tasks off once I have assigned them to a daily log. Obviously I also have my daily log pages, then I also have some pages about work placements, books read/reading challenge, megalist, and financial planning, so far.
Sitting down for 5 minutes or so each evening to sort out my next day has become quite a pleasure! So thought I would finally join in and say thank you for giving me the final kick to get BJing
