In theory, most of us would rather be frogs than tadpoles, but we don't quite trust it, and shrink back from the transformation process. We live as if we were going to be tadpoles forever. Usually they know the right words, but they haven't experienced any of it directly and don't really believe very much of it. The Sages know that we tadpoles will become frogs. They chuckle at our attempts to believe it.
Some tadpoles spend a fair amount of effort giving the impression that they believe it.
But it will happen in any case.
