Strength of character means the ability to overcome resentment against others, to hide hurt feelings, and to forgive quickly. – Lawrence G. Lovasik (Multiple attributions)
The strength of your character is developed not just in the good times, but is forged in adversity. People rub you the wrong way and rather than hold them in contempt, you overcome the resentment. When your feelings are hurt you learn to let it go and forgive. Is it easy to do? Of course not. But few things in leadership are easy and there are no shortcuts in developing strength of character. But you will be a better person and leader when you find your strength and lead with your head and heart.
