I have been working in the field much more lately and have been so good about not carrying big, heavy bags. I do not carry my laptop or documents with me unless absolutely necessary. For lighter days, I stick to a small bag and I hold it in my hand, not over my shoulder.
To further lighten my load, I have changed from a personal-sized to a pocket-sized planner. It is a long time since I have been in such a small size, but I decided to try it out for a while. It holds the bare minimum and so far has been a success. I cannot believe that for years and years I only used A5!
I have a few pocket sizes to switch between, but to start with I am in my Gillio Mia Cara in Epoca Gold. This is a first generation Mia Cara and was produced in about 2009 I believe. They are quite big and bulky due to the outer cover, but in pocket size it is manageable, and the extra space more than makes up for the small rings.
I have only just noticed (after almost ten years!) that both my first generation Mia Cara covers have square corners at the top, and rounded ones on the bottom. My later versions have square corners top and bottom. Strange!
