Bullet Journal (or lovingly Bujo) is an analogue system that was created by Ryder Carroll of Brooklyn. The ironic thing is – he is a digital product designer! In spite of dealing with technology, he recognised the need to have a flexible analogue system that can combine to-do lists, diaries, notebooks, sketchbooks and anything else, depending on your needs, wants and lifestyle. Please have a look at his video below and his website www.bulletjournal.com explaining the system. The beauty of Traveler’s Notebook is that you can use different refills to cater for your needs. When you adapt this system, you will be doing it your way and different Midori refills will certainly help you on your way.
