It isn't something new, it's something long forgotten old. Many years ago, than there are no computers and mobile phones, we wrote our diary and work lists by a pen or a pencil.
I agree, It's useful for our memory and psychic. This method eliminates unnecessary activity and communication. I'd love to keep a journal like this. But! How do I write down links in a book of paper?
I think for comfortable planning It's necessary to keep two bullet journals. One of them should be an electronic version, the other a paper version.
I'm sure, this blog has enough tolls and options for keeping bullet journal. Such a journal will be available in anywhere. I can write some terms in the paper version and save web links and quotes in electronic version.
Two journals won't be copied from each other. They will complement each other. Sometimes, I can reference on electronic version in my paper version.
To be honest, I have been keeping bullet journal but I haven't been writing in one whole book. All my notes are in disarray.
Now, I'll try to put them in order.
