That advice reported by Nassim Taleb as the best advice he ever got from a friend, near the end of his book, The Black Swan back in 2006.

If you don’t happen to live where there are trains to catch, you might rephrase:

Don’t race for green traffic lights. And even less for yellow.

When I was in second grade, we were sent home several times a year with a newsprint folded order form for Scholastic Books. The contents were not all books. There were also inspirational posters with pictures of kittens and puppies. One of them – one of only two I remember – had a picture of a kitten with the words:

The hurrier I go the behinder I get.

The other one I remember also had a kitten on it, and said:

Sometimes I sits and thinks. And sometimes I just sits.

I suppose they are the only two I can remember because they were the only 2 worth remembering.
