During the eighties I kept a diary. In the nineties I used a Palm Pilot and Outlook / Exchange to keep myself organised.
For the last three years I have gone back to paper, or at least a mix of paper and computer.
I work in IT for a large outsourcing organisation and support a number of companies. Due to data and privacy rules my work diary is encrypted and accessible on my laptop and work phone. My personal information and my part time job as a photographer is now a mix of electronically held information for data that needs to be shared and my paper journal.
My paper journal is also a mix of things, its a bullet journal for everything and a personal diary. Over the last year I have been looking at the William Hannah products.
Its a simple leather bound A5 ring journal but incredibly well made and I have been lucky enough to be bought one for Christmas.
I spend yesterday setting it up as my new 2020 bullet journal and am looking forward to using it to plan my future 2020 shoots.
