Being a nice guy (or girl) takes lots of practice, patience and
  staying nice. ''Nice'' is seen as a weakness or stupidity by
  some, but if you do it right, you will be happier in the face of
  a very unhappy world. To be nice means to give people the time
  of day when they ask you, to say ''hello'' when you want to just
  look at your feet. it's easy to ignore people. But it takes a
  strong person to let people in. Your heart is exposed and
  vulnerable but it keeps beating, stronger and stronger.
