The best camera you have is the one you have with you.
The best notebook you have is the one you have with you.
When I have an idea, I jot it down in my phone via Apple notes. Pen and paper are more classic, but capturing a thought on my phone is so much more convenient because I always have my phone with me.
Working from home during COVID-19 means I’m at my desk and in front of my computer for a large part of the day. The upside of being close to my mac is that memorializing ideas is so easy when I have a keyboard at my fingertips.
The downside with walk & talk meetings or impromptu chats in an office, was that I didn’t immediately write down what had happened or what I needed to do next. Stuff slipped through the cracks. Ideas got lost in the fray of the day.
Writing something down gets an idea out of my head and makes it real. That’s a huge first step to getting it resolved, publishing it, or codifying it.
