Doubt comes from the inability to see the inner self; one sees only the effect of the self.
Look at the inner self within others and not just their expression.
Doubt is removed by a clear appreciation of the true self.
Work to understand what part of you is expressing and what is the expression.
The person in self-doubt is at the mercy of things.
Self-doubt is the lack of appreciation for a reason to exist.
Doubt not.
