Anatomy of a Bujo

Because this is YOUR journal only you can decide what pages you need and what is pointless for your life.  Anyone who Bujo's will tell you just try it.  If you hate it there is nothing lost.  Over time you develop your style.  The flexibility is AMAZING!  Here's some common pages and my personal thoughts on them...

Key - beginning of your journal; lists all the ways you will be marking or flagging items. 
Personally I like to continue to make a key even though after all these years I know what my marks mean.   These can be added to over time as you need more identifying marks for your tasks.

Index - beginning of your journal; lists the locations of your collections for future reference.
At some point we all need to look back at what we did and when so this has been useful and I do still make one (although I am very bad at keeping it up to date).

Future Plan - a page where you can list things that are upcoming for the next 6 months so you are not trying to remember or having to plan out too far.
I tried this one and used it once so it is no longer in my journal.  I pre-make monthly calendar layouts for the year and use that for my future planning.  I found this didn't work for me but you do need some place to write future events so I suggest seeing if it works and adapting if it does not.

Spreads - can be yearly, monthly, weekly or even daily; this is where you will list tasks
How you like to view your items is a completely personal choice.  What I found worked for me was starting with a monthly calendar for events and a daily running list with no set format to limit your space.  As you see how much you typically have on a given day you can adjust accordingly and decide if a weekly layout will work or if you have too many items each week and it would get cluttered.

Trackers - fitness, weight, bills, inventory, food, water, savings, etc.
These can be anything and are very useful.  I have found some I use and others that do not work so this is another that I suggest trying and tweaking to see how you like them.

Recaps - as often as you like and it is a reflection on that time.
While I can't say I do these I think it is a FANTASTIC idea!  I love the idea of reviewing the past month or year and giving an honest opinion on how you feel you did and what you can improve upon.  The nice thing is that all the information is right there at your fingertips!  This is also a great way to get that sense of accomplishment for those who feel they haven’t made a dent in their to do list!
