http://www.bulletjournal.com/I think I got this off of /edu/, maybe here even, anyways I'm going to give my thoughts on it.
Basically. It sucks. At least it does for me. Instead of "relieving you" of things you'd otherwise forget I wound up having open checkboxes for stuff that just couldn't get completed on that particular day, writing inconsequential stuff, and all sorts of petty things like that. With stuff that doesn't get completed either you leave them open (fucking shreked my ocd ass) or you wrote the damn thing down again on a new day.
Inputting was a bitch too. I have a tally book at work that i use to write down quick notes, names, tips. Because of fear that they would get lost I usually immediately get to work on it. If not, I wrote it down on a sticky note on my desktop. Works perfect because my computer is usually where i'm at and the tally book is on me like 90% of the day.
With the bullet journal i wrote stuff down and actually forgot because it's a pain to pull the mother out, read/log stuff in, cross shit out. Visually it sucked as well because to me it's just not as satisfying seeing a box checked compared to deleting an entry completely on my screen and makes it so that it rapidly takes up space
Really, it's just complex for the sake of being complex. Simple is best. What I do is write my goals for the year down on a word document, break them down in general terms and chug away rather than repeating the minute aspect of it all. It's simple and keeps me focused on the big picture(s) where as the bullet journal side tracks you constantly when you have shit that frankly doesn't matter at the forefront. A shopping list with the system takes priority in your head over the long term goal.
I will be no longer using this system. It's inefficient, complex(i say that term lightly btw) for the sake of being complex, and really didn't fit into my day to day routine.
The KISS method wins yet again.
