Confidence is a plant of slow growth; especially in an aged bosom

If your confidence is based purely on the way you look, you’re setting yourself up for a) years of fretting about how to appear perfect, and b) anxiety / despair as the wrinkles inevitably set in.

Base your self-belief on what’s in your heart and mind; you’ll never lose your inner beauty.
