More about Bullet Journal:
The basic idea of Bullet Journal is great, but in practice, I use this system for my sketches (for now). My sketches of different projects are well organized. As a planner, this system does not work for me because it takes too much time to prepare for planning in advance. But I love to look other Bullet Journalist that inspire me and sometimes I want to give it one more change.
For now, I use Bullet Journal system in my regular planner. And it works great for me! How? I use Bullet Journal keys in my planner:
|X||for completed tasks|
|>||for migrated tasks|
|*||for important tasks|
|–||for canceled tasks|
With this system is my planner even more organized. Every time I look at my task I immediately see what I have to do and I focus only on tasks without any marks.
