I don't. I just assume the words are different enough from one day to the next that I should switch it up.
I think there's some good starter words to use, just to hit as many "big hitter" letters as possible. Something like "teams", "cream", "deans" are what I usually go for.
3/6 again today I don’t have a set word to use just something that will knock out two vowels and common consonants like t/s/n/m/r.
