Right, these are fairly old now, but I still find myself watching them whenever in need of some inspiration - this was pretty much the mantra by which I wrote my thesis (as corny as that sounds). Music's a pretty good fit too.

One thing is that 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, in different degrees of certainty, about different things. But I'm not absolutely sure of anything and of many things I don't know anything about, such as whether it means anything to ask why we're here and what the question might mean. I might think about it a little bit, if I can't figure it out, then I go onto something else. But I don't have to know an answer. I don't feel frightened by not knowing things, by being lost in the mysterious universe without having any purpose, which is the way it really is, as far as I can tell, possibly. It doesn't frighten me.
