To echo the sibling - I believe the most important skill a developer can have is reworking* code, and doing it readily and continuously. If you can do that, then you don't ever have to worry about what code MIGHT do in the future, you just design it for what it DOES do and then rework it later if necessary. It's quicker and the result is cleaner. Also, even if you tried your hardest to predict what was going to be needed, there are always things you can't predict and at that point you either rework your code or have bad code. * I could have said refactoring, but some people have very specific definitions attached to that word so I use something more general here
