The greatest glory in living lies not in never falling, but in rising every time we fall.
Success is not final, failure is not fatal: It is the courage to continue that counts.
The best thing about a picture is that it never changes, even when the people in it do.
Do not go where the path may lead, go instead where there is no path and leave a trail.
The most beautiful thing we can experience is the mysterious. It is the source of all true art and science.
