A clickbait link popped up on my phone with songs that were written in less than 20 minutes (I am linking to another post with the same subject).
Yes, these songs might have been written in 20 minutes, but I am sure that those 20 minutes are the result of years of practice, trying, and noodling by these musicians. All that effort that was built over a long time just fell in the right place.
I think this is true for every creative process, including presentation design and storytelling. In Hemmingway style: ‘gradually, then suddenly”, Seth Godin talks about it in “The Dip”, a tank filling up drop by drop until it finally bursts with great force.
