Perseverance

"Courage is not having the strength to go on; it is going on when you don't have the strength."

"Success comes from curiosity, concentration, perseverance and self criticism."

"The greatest glory in living lies not in never falling, but in rising every time we fall."

"Run when you can, walk if you have to, crawl if you must; just never give up."

"It is during our darkest moments that we must focus to see the light."

"There's only one way to succeed in anything, and that is to give it everything."

"Success is not final, failure is not fatal."

"Perseverance and spirit have done wonders in all ages."

"However difficult life may seem, there is always something you can do."

"Fall down 7 times, stand up 8."

"The woods are lovely, dark, and deep. But I have promises to keep, and miles to go before I sleep."

"Success is not final, failure is not fatal."
