What do you write on a daily basis?

All this self loathing for not being able to write anything has me wondering. What kind of things do you use your notebooks for on a daily basis? I see plenty of people listing their #dailyarsenal on Twitter and I always wonder what they use it for.

So tell me, what do you use your notebooks for? Are you journaling all day? Jotting random notes? Formulating your latest plot to take over the world?

Inspire me, I feel so lost.
