We gain strength, and courage, and confidence by each experience in which we really stop to look fear in the face... we must do that which we think we cannot.

That which does not kill us makes us stronger.

Character cannot be developed in ease and quiet. Only through experience of trial and suffering can the soul be strengthened, ambition inspired, and success achieved.

Do not pray for easy lives. Pray to be stronger men.

The world breaks everyone, and afterward, some are strong at the broken places.

Continuous effort - not strength or intelligence - is the key to unlocking our potential.

Strength does not come from winning. Your struggles develop your strengths. When you go through hardships and decide not to surrender, that is strength.

I love those who can smile in trouble, who can gather strength from distress, and grow brave by reflection. 'Tis the business of little minds to shrink, but they whose heart is firm, and whose conscience approves their conduct, will pursue their principles unto death.

Out of suffering have emerged the strongest souls the most massive characters are seared with scars.

Only one who devotes himself to a cause with his whole strength and soul can be a true master. For this reason mastery demands all of a person.
