Came across this article while looking up some tips for starting bullet journal. This is pretty close to how I started, only with dailies, and then added other stuff over time.
Can be helpful for someone who is feeling overwhelmed with starting a bullet journal. You can just leave couple of pages on start empty, and start with daily log, and then fill in the other parts later, once you are used to it.
Yes, you can say that. Though there are different types of habit trackers, some are incorporated in monthly spread. The article mentions just adding first letter of your habbit on the day you do it. So, that's one way to do it. Or you could make a separate "collection" page.
Like everything else it seems like you can make it however you want to. It would be easier to track over months but maybe not as easy to remember to do. Probably depends on the habit.
The number of people who have told me they had given up on trying BuJo because they 'weren't artists' and couldn't do all the stuff... first thing I tell anyone asking about BuJo is that if a 'how to Bujo' thing says they need more than a notebook and pen, it's a bad intro.
