"I was forced to go to a positive-thinking seminar. I couldn't stand it, so I went outside to the parking lot and let half the air out of everybody's tires. As they came out I said, 'So, are your tires half-full or half-empty?' "
Trying to think positive never really worked for me. It came naturally after I DID what was necessary to get what I wanted in life. Yes, it's a requirement, but I think we place way too much emphasis on forcing it...rather than seeing it come as a result of doing.
