Richard Feynman Quote
"I can live with doubt, and uncertainty, and not knowing. I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers and possible beliefs and different degrees of certainty about different things, but I am not absolutely sure of anything and there are many things I don't know anything about, such as whether it means anything to ask why we're here...
I don't have to know an answer. I don't feel frightened not knowing things; by being lost in a mysterious universe without any purpose, which is the way it really is as far as I can tell. It doesn't frighten me."
