I also have one big notebook that serves as a day to day scratchpad for projects that I'm working on, and a smaller notepad that I use as my daily to do list. Every day, the first thing I do at work is pull out this smaller pad and jot down a quick task list, by hand. I've tried the online task lists (I'm basically addicted to trying them) but at the end of the day I still go back to the old school pen and paper approach. Whatever works for you.
Aside from the prinouts, notepads and obvious stuff like monitor/laptop, I have a coffee mug and nice pair of stereo headphones for when I need to tune out.
That specific enough for ya?
And the usual stuff Macbook pro + screen (don't buy apple, better get Dell or Samsung with 4k) + stand + logitech K760 + some cheap mouse
Bought it in the UCF bookstore for about $100 in the spring of 1989, the unusual thing on my desk is an HP11C. Now in its 26th year, it's still a goto device.
Its how I sit when I read HN.
