Bullet Journal

That's a coincidence : I just bought an Arc Notebook[1] from Staples with the express will to try this (I really like to be able to rearrange pages). So far (a few weeks), it's going very well. I tweaked the process to my taste but the idea remains the same.

I really wanted to implement my calendar and todo-workflow on my smartphone. The idea of having everything synced everywhere and to be able to "do" stuff everywhere was really compelling. A few months later, I'm back to paper and pen because the feeling and the level of control is so much better when I write.

Another thing I realized is that I'm a doodler. My to-do lists are messy, filled with small drawings but I still understand everything. Fitting them into a computerized list feels like trying to insert a square peg into a round hole.

I know that my journal won't scale easily, but I can't imagine being way busier than I'm now for a little while.
