The greatest danger for most of us is not that our aim is too high and we miss. But that it is too low and we reach it.
  -Michelangelo

Never, never, never, never give in.
  -Winston Churchill

Stay Hungry. Stay Foolish.
  -Steve Jobs (from commencement speech)

You miss 100% of the shots you never take.
  –Wayne Gretzky

There is a tide in the affairs of men
Which, taken at the flood, leads on to fortune;
Omitted, all the voyage of their life
Is bound in shallows and in miseries.
On such a full sea are we now afloat;
And we must take the current when it serves,
Or lose the ventures before us.
- William Shakespeare [Brutus in Julias Ceasar]
