My approach has changed a lot since I started home-brewing.

But it now boils down to something like this.
I figure out what I want a thing to be able to do, see if there is something that either already does that, or does something similar to it, then use as similar language as possible to the original thing. Editing for personal preferences (I loath using the word "you" in my text.)
Balance is tricky, but I figure so long as everything that exists has an equally difficult (or equally easy) to access counter at the same level, it ought to be kosher.
And then compare to precedent.
Oh, and I like to add in a metric pants load (roughly 1,000 kg) of options.
