* It (usually) doesn't have to be perfect the first time. Programming is an interative process and your first attempt is going to have bugs, or make faulty assumptions about the problem.

* A design which can be generalised is inherently more complicated, and is often unnecessary (you probably won't make use of that generality, leaving you the burden of maintaining it), so you'll be glad you made a simpler first pass.

* I don't like working with docker/containers personally. It makes me feel so far removed from how services are deployed that it's basically magic.
