But to be optimistic—we do. We have to read books, watch seminars and conferences on how to be positive and motivated, etc. We seek training and correcting because we really do recognize how detrimental being negative/pessimistic really is in most things such as business, sports, gambling and relationships.
Then there is the hard-core, which are plentiful as well. The people that are optimistic about being pessimistic. A real double-edged sword. Those are in a league all their own and they are the outgoing, extroverted and humiliating, pessimistic primed-person.
Ever notice how people will comment, "Wow!! I just saw 'so and so' on TV (or in person) and the great accomplishments, great things he/she did"!!!! Everyone comments when someone is pessimistic and really positive, motivated and employing the pessimism is their job or sports.
