Recognize your highest calling as early as possible in life.
Make a difference. Live a life that matters.
Many of us are fortunate to be blessed with the ability to succeed - not for our sole benefit, but so we may apply the result of our success to assist others.
Act with integrity. Live up to your idea of who you are.
Proactively, and creatively, persist - day in and day out.
You cannot brighten another's path without lighting your own.
