You should read the whole post but what stuck out to me was the hybrid analogue and digital tools he uses. He says he uses and needs both.
I'm 99% analogue for my personal organization of tasks. I use Trello with clients, and am dabbling with Github Issues/Projects/Milestones as an alternative.
Every so often I feel overwhelmed and break out Things 3, but it's always been long enough that I just wipe the remote database and start from scratch. It lasts a few weeks and then I drop Things 3 again in favour of my analogue only approach.
If you're interested, I wrote a book about what I do called Analogue Productivity
