There are warning signs that we all can see...
And then there are the quieter warning signs. One of the most common of those is "ish".
- Sure, that's trivial... ish.
- We'll be done in August... ish.
- That's a smallish change.
"ish" here is code for "I don't know, exactly"; it's the verbal equivalent of waving your hands in the air vaguely. It's not bad, necessarily. It just means that something may change in the future.
So watch your "ish" and give yourself a bit more wiggle room when your task is a bit fuzzy.
