Does anyone know the source of this?

A philosopher said that someone who is enlightened should not concern themselves with changing the minds of ordinary people. He compared it to situation in which it was raining outside in a city, saying it was better for the philosopher to stay inside than try to convince people outside that it was raining and in the process get himself wet.

I think it was Plato but I can't find it anywhere
