“If you don’t have anything nice to say…”
…then you’re a grouchy, uncreative person. There is always something nice to say. It doesn’t have to be about the thing right in front of you. You don’t have to put a silver lining on every cloud – sometimes you just stub your toe on a rock and that doesn’t need a positive spin. But that toe-stubbing didn’t erase every good thing in existence!
So you don’t need to say something nice about everything. But if you ever think there’s nothing nice to say at all, that’s on you, not the world. The world is just the net total of all the good and bad we humans put into it. Put some more good in it.
The sun is always shining somewhere!
