"Drive, competitiveness and determination. Commitment. These are the qualities we associate with winners. But each one of these characteristics depends on one other: optimism. Without optimism – that gut-level belief that we can succeed – we are far less likely to realize our dreams. Setbacks and slumps will stop us cold if we don’t have basic faith in ourselves. No matter how badly we want to succeed, if we don’t feel optimistic about our abilities and our potential, every day is going to be a struggle."
