The hallmarks of successful small business owners:

The humility to admit you can't do it all and the courage to ask for help. The humility to recognize failure and the courage to assume personal accountability. The humility to concede that ownership is not mastery and the courage to never stop learning. The humility to stop chasing certainty and the courage to accept risk. The humility to accept criticism and the courage to reward it. The humility to empathize with employees and the courage to share your wealth.

When humility and courage are a part of your culture, your business is unstoppable.
