"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"

This quote by Leonardo da Vinci talks to the self-control and resilience of those who can discover joy and strength in difficult times. He is applauding those who can remain favorable and brave in the face of difficulty, and who can review their experiences to become more powerful. He is likewise contrasting these people with those who are quickly overwhelmed and dissuaded by life's difficulties. He is suggesting that those who have a strong sense of morality and conviction will stay true to their principles no matter what. This quote is a pointer that we can all discover strength and nerve in challenging times, and that we ought to make every effort to remain true to our values and beliefs.
