I continue to remain astonished I was ever able to research and write an entire non-fiction book about a wide variety of topics without the aid of the wonderful (and free) Obsidian app.
Don’t get me wrong: other perfectly good ‘Personal Knowledge Management’ apps are available. They’re very much the in thing at the moment. But how was I ever able to organise my thoughts without atomising them—breaking them down into smaller and smaller discrete notes—and then linking them together? How did I ever manage to get my head around complex, interrelated subjects? How did I ever spot interesting unexpected links between apparently unrelated topics? How did I ever see the wood for the trees?
I managed somehow, but this new way is far better.
I can never go back.
