That post above might have sounded odd. All I was trying to say is that sometimes adversity and negativity can sometimes be a positive influence. Tyson speaks about his boxing career and how nervous and scared he could be before a fight. Yet those feelings allowed him to channel it all into an awesome career prior to the prison fall. Nobody is thinking positive things going into the ring, or getting ready for a lecture, or chasing someone in a police car, or climbing Everest. You are getting the job done. In real life and situations that are pressurised and in the now, you can't be feeling positive and in many instances it would probably be a detriment to your performance. I think there is a time and place for being positive and having a laugh, but you have to be serious to get the real work done.
