The Index Pages, the Key and a Future Log Idea for your bullet journal
A reset in your bullet journal
If you are starting a bullet journal, the first proper pages you’ll keep are your Index pages and then your Key.
If you are following the bullet journal system or you want to reset your journal, at some point, you might want to make a Future Log.
The Index Pages
At the beginning of your bullet journal, you should leave a couple of pages for the purpose of an Index. As you make further headway into your bullet journal, you will copy out the titles of your pages on to these index pages and include the relevant page numbers.

The Key
The key in the bullet journal system includes:

You can cutomise your key to suit your needs. If you have to record a certain type of information that you know is going to crop up time and time again, you could create a symbol for it and add that to your key.
A Future Log Idea
The Future Log is for you to get an overview of your coming months. You can set this up how you like.
For example, you may decide to make an overview for the next 3 months only. You could also do a double spread so you can fit in an overview for 6 months.
Note down any important dates, events, holidays and deadlines etc. These can be migrated forward when you have made the relevant monthly log.

As you can see in the above image, I decided to reset my bullet journal after 70 pages of use. I wasn’t using a Future Log before and some people in fact, don’t. That is ok too.
I have put my Key and my Future Log together — they’re on the same spread. My current Future Log is for 3 months. I may have more information to add for August afterwards.
I hope you understand that you can reset your bullet journal if you want to re-commit to following the system, or even if you just want to change things up a bit.
If you are just starting a bullet journal, you now know how to set up your first few pages and what their uses are.
Good luck!
