How many people does it take to make or break your career?
How many close friends does it take to alter your life forever in a positive way?
How many times do you have to win a Grammy to be called a Grammy winner? Or a platinum selling artist?
Then why in the world are we all trying to be involved in as many people's lives in the most superficial way possible (i.e. Facebook) and spreading our talents out among dozens of insignificant projects to the point that we do none of them well?
Make a decision today about what's important, and then stop pursuing the things that aren't.
