Work hard in silence. Let your success be your noise.

I am strong because I have been weak. I am fearless because I've been afraid. I am wise because I have been foolish. 

Never speak from a place of hate, jealousy, anger or insecurity. Evaluate your words before you let them leave your lips. Sometimes it's best to be quiet. 

Matthew 5:6

"Blessed are they which do hunger and thirst after righteousness: for they shall be filled."
