Creativity is a wonderful thing, when you can capture it.
Creativity can be fleeting. Capture it when it strikes.
I’ve always done my best slow thinking with pen and paper. I’m a child of the 80’s, it just seems like I can translate thoughts in my head into actual words best this way.
If pen and paper aren’t nearby my phone almost always is (much to my wife’s chagrin). The notes app on my phone is super useful. Voice recording apps are also super handy.
The key is capturing that thought or idea in its purest form before you can over analyze, edit or ruin it.
