Self-confidence is not the same as arrogance. Arrogant people often don’t listen to others and try to ramrod their way through life. Someone with self-confidence knows they are not perfect, but they also know they have at least the common sense to work out most everyday problems and challenges in a perfectly acceptable way. They accept the fact that sometimes you win and sometimes you lose, and go on with their lives. Arrogant people try to be perfect, and when they fail, their unhappiness can be epic. Exercise that grin each morning and use it on someone who might need it—a co-worker, a family member, a stranger. Spread a little kindness to get a little happiness back.
