Anonymous: What's one thing you know for sure?
That the easiest way to end up looking a fool is to say “I’m certain of this.”
Doesn’t stop me from doing it, mind you. I look like a fool most of the time. That said, I have little use for folks who don’t have opinions, who say, “well, you can’t know anything for sure.”
Of course you can. Life will eventually find a way to add to your knowledge, and you just might end up changing your mind. But at least you started with a point of view.
