When you know your gifts and what you can do with them, you begin to know who you really are. There is great power in this knowledge.
When you know who you are but remain constantly aware of your failings, that is humility.
When you know who you are, and you are not afraid of doing it—when you are unafraid of making mistakes and of the opinions of others—that is confidence.
Notice that humility and confidence share the trait of knowing who you are and what you can do. Humility and confidence are partners. If you have both, you will experience great joy and be of great service to those around you.
