"The work of intellectuals is ordered and paid for by Governments or rich men, whose aims probably seem absurd, if not pernicious, to the intellectuals concerned. But a dash of cynicism enables them to adjust their consciences to the situation." - Bertrand Russell

Two somewhat related quotes:

Short version:

"Bad shit is coming. It always is in a startup." -Paul Graham

Long version:

"First, and most importantly, realize that a startup puts you on an emotional rollercoaster unlike anything you have ever experienced.

You will flip rapidly from a day in which you are euphorically convinced you are going to own the world, to a day in which doom seems only weeks away and you feel completely ruined, and back again.

Over and over and over.

And I'm talking about what happens to stable entrepreneurs." -Marc Andreessen
