The day I find a cabinet like that at the local “marché aux puces” I will probably do a paper Zettel as well. It’s beautiful and fulfilling.
Allow me to correctly rephrase that sentence of yours: "the day you find a cabinet like that at the local “marché aux puces” you instantly send me a message to ask me if I want it". Which I am, and I will thank you wholeheartedly, even though I had no idea where I could put it in our small apartment ;)
You're welcome ;)
If you decide to give a try to a Zettelkasten and if I was to share a single advice it would be to keep it simple. Ignore all subtleties, you will know it when you need them.
