"Just because you fail once, doesn't mean you're going to fail at everything. Keep trying and believe in yourself."- Marilyn Monroe.
Giving up only means you are giving up on yourself. Our life decisions are not written on paper. We must face the obstacles life throws at us, and learn from each decision. There are no mistakes in life, just lessons learned. We will fail, but from those lessons learned we can move on and keep trying. =)
