“5. Lack of self-discipline. Discipline comes through self-control. This means that one must control all negative qualities. Before you can control conditions, you must first control yourself. Self-mastery is the hardest job you will ever tackle. If you do not conquer self, you will be conquered by self. You may see at one and the same time both your best friend and your greatest enemy, by stepping in front of a mirror.”
“It should be recognised as a crime (in reality it is a crime of the worst nature) for any parent to build inferiority complexes in the mind of a child through unnecessary criticism.

Criticism will plant fear or resentment in the human heart but it will not build love or affection.”
