Get a whiteboard. Big or small. I usually scribble a lot on it. Simple strategy, roadmapping, to-do list etc.
I look at it as #productivityhacking
I bought another whiteboard today, it's the same size as the older one - 5ft. x 4ft.
Why? - I am getting more and more used to scribbling on these whiteboards. I need one to have more perpetual thoughts and tasks. This would have long term tasks.
The older board will still continue to be for notes, planning, small to-dos etc.
