Dumping all those thoughts that bang around in your head out into a place.
It could be an analog place like a dedicated notebook (bujo anyone?) or a collection of sticky notes affixed to your desk or monitor.
It could be a digital dumping ground like Omnifocus, Habitica, or Todoist. Maybe even the good old reminders or notes app or a cloud solution like Google tasks or keep.
What matters is that you do it consistently.
To the same place anytime you think of something. Then, you revisit that list. That is for another post though.
Choose your weapon right now.
Paper and pen will do.
Write down everything rattling around in your head no matter how big or small.
Now grab some hot chocolate and watch some Hulu.
