Whatever you are by nature, keep to it; never desert your line of talent. Be what nature intended you for, and you will succeed. (Sydney Smith, 19th century English writer)
This is good advice for people who constantly wish they were someone else. God created you with all you need to accomplish His purposes for you and to find fulfillment in realizing them. Success is not measured by individual exploits so much as by the totality of one’s achievements in keeping with his talents and abilities.
May he give you the desire of your heart and make all your plans succeed (Psalm 20:4).
