Doubt kills more dreams than failure ever will. (Suzy Kassem, author and philosopher)

When you fall down, you hurry to get back up. When you fail at a task, you try again. But, if you doubt you can fulfill your aspirations, there is little you can do to achieve them. It’s not so much your self-confidence that will help you succeed, but your determination not to allow doubt and the fear of failure to stop you and your trust in the God of hope.

Blessed is the one who trusts in the Lord, whose confidence is in him. (Jeremiah 17:7) So do not throw away your confidence; it will be richly rewarded. (Hebrews 10:35)
