Never think or speak negatively about yourself that put you in disagreement in or with God.
Don't compare yourself to anybody else. You are unique, one of a kind and original. So don't settle for being a copy.
Meditate on your God-given strengths and learn to encourage yourself and others, else nobody will.
Focus on your potentials not your limitations. Remember, God live in YOU.
Have the courage to be different, be a God pleasure not a people pleasure.
Learn to handle criticism, since you don't see yourself well (you do use mirror), let it develop you instead of discouraging you.
keep your own worth instead of letting others to do it for you. In this case, watchout for your pride.
Always check and follow your conscience for good, God is watching you.
please forgive offences, because it liberates your soul, remove fears and refresh your bones, what a powerful weapon.
YOU ARE GREAT AND SPECIAL.
