I've got to confess I'm a pragmatic optimist myself.
Stop being afraid of what could go wrong and Start being positive about what could go right.
What defines us is how well we rise after we fall.
Failure is an event, it is not a person.
You measure success by how much good you do for others.
You build a successful career, regardless of your field of endeavor, by the dozens of little things you do on and off the job.
