@luca Vibing your own solution is also a way to never have to think about whether your workflow makes sense. Say, you want a customer relationship database. If you look at existing software, none might fit the way you have been working so far with just Excel sheets or whatever. But maybe your workflow was inefficient and you've just entrenched it.
Existing software might work differently because people with more experience have concluded that it makes more sense to do things in a certain way...
