"Anyone developing new products and new technology needs one
characteristic above all else: hope. This comes down to a few elements:

• having high expectations that you will succeed – despite any setbacks
  or frustrations
• having the sense to break down an imposing task into
  smaller, manageable ones
• believing that you are able to achieve your
  goals, whatever they may be. Be dogged and determined
• and don’t be
  afraid to be different."

– James Dyson
