Great Quotes about Hard Work

I have been trying to find this quote for a while, and today I finally found it. I remember first seeing it in a friend's office and liked that she felt that hard work was the answer - no questions. She worked hard, that's for sure. Anyway, here it is:

Nothing in the world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination are omnipotent. Calvin Coolidge

A few times I've mentioned how important it is to me to continue in the face of adversity. Hopefully, I'm not only persistent, but maybe a little talented and educated so it makes for a good combination. But I have to admit that of the three - persistence is the thing I value most. You have to continue.
