"Too much knowledge could be a bad thing. I was lead to the Szemerédi theorem by proving a result, about squares, that Euler had already proven, and I relied on an "obvious" fact, about arithmetical progressions, that was unproved at the time. But that lead me to try and prove that formerly unproved statement- about arithmetical progressions-and that ultimately lead to the Szemerédi Theorem."

Fear is crippling. Fear of the future can convince us that there is no way out and nothing is ever going to get better. Fear is blinding; it can make us miss the warning signs flashing right in front of our eyes. It can also make you miss those brilliant flashes of color, when the world isn't so gray. But, if you think about it, being afraid isn't such a bad thing. Because fear is a reminder that you still have something to lose. Something worth holding onto.
