There are so many ways you can add value to yourself but the best of all is through the Word of God for through it you can sharpen your mind, grow your intellect and wisdom and improve the quality of your personality AT WILL.
Therefore always tell yourself: Am anointed to be wise and intelligent; I have the wisdom of the ancient cos the ancient one lives in me; I make wise choices supernaturally cos all the wisdom of God resides in me and I have full access to divine intelligence!
It's better to pattern one's life on principles than on people's experiences cos in living by people's experience, you can be mislead if you're not careful.
