Woody Allen once said that "eighty percent of success is showing up."

To me, that means, you go to the meeting about the project.  You're there anyway.  May as well participate.  There's another way in which you can help out and use your skills.  Ok, well then, you're there, may as well show up for that as well.  And so the cycle continues.

Show up ->  you're there anyway, may as well pitch in.  You're pitching in, may as well do it well -> Show up...
