Hard work beats talent if talent doesn't work hard. Don't be content to work around the edges of your profession. Speak up. Volunteer. Show your enthusiasm. Knock on doors.

People don't care what you know until they know that you care. Success is always a team effort, and no one does great things alone.

Remember that hope is not a strategy. And problems don't go away when you ignore them — they get bigger.
