I don't code, at best I script. I'm a sysadmin, not a dev, so I play around in PowerShell mostly.

I just started to naturally do all of this. Not because I was taught to, but because I've written too many scripts that I later looked at, and thought, WTF is going on here.... Who tf wrote this? (Of course it was me)...

So instead of confusing my future self, I started putting in comments. One at the beginning to describe what the file name can't, and inline comments to step me through what's happening, and more importantly why I did what I did.

The sheer number of comments can sometimes double the number of lines in my script, but later when I'm staring into the abyss of what I wrote, I appreciate me.
