There are some lovely bullet journals out there. I am not that artistic but I am learning that a little colour really helps me to smile.
As I have said I don't like being held to one style of layout or size of space so I don't draw up my days, weeks or months in advance. My bullet journal is definitely a mood thing, whatever space I need is the space I use. :)
I usually add the colour later. And I only create the headings that suit my day. A very personalised way to journal.
Some days are more list based and others are more journal like. The blank pages are so freeing. I can do whatever suits me.
Because I dread losing all these entries (I have lost a paper journal before and I fear coffee spills) I scan them into OneNote then put tags beside the page when there is something written there that I may want to reference later. I scan them as images as they are easier to crop and my books are 3/4 A4 pages.
Anyway, that is my way to bullet journal.
Best wishes
