Do you complain about work, about your co workers, about your wife, your kids, not enough money?  Do you complain about having to work out to keep in shape, about having to be so strict about your food intake?  Do you let people annoy you?  Are you willing to learn new things?  Are you willing to create new solution.   Are you part of the problem?  Do you have good systems in place to exercise, to eat healthy.  Is complaining just a habit?
