But there's a reason for this too: deadlines.

I have written all sorts of implementations for things that I'm positive there's a library or existing example out there that is just plain better and more thorough.

The problem is, I don't know what it is. I don't know where it is. And finding it will take time, take effort to evaluate the non-good implementations, and take effort to integrate with other systems.

Whereas I can write code now which is "good enough" (or worse, just not good at all but exists and does something right now) and then move on and hope I'll find the "better" I'm looking for later.
