Also from 37signals, somewhere in their first book they talked about the importance of 'evergreen' things people always want, things like 'the speed of software'. As a junior dev I didn't really get the point or thought it was not that important. I browsed further in the book looking for other gems of wisdom, and this 'speed'-thing only stuck in my head for the wrong reason, thinking it was a little obvious for such clear writers with a solid vision. Only 15 years later - now a couple of years back - I started to realize the importance of this. The apps on my smartphones seemed to get slower and slower by the year. The fast software experiences were a real joy amidst slow apps. I now have an appreciation for their opinion on 'evergreen' things like the speed of software.
