Definitely is a profound quote. If only I can script it into my brain and internalize it so much that my thinking doesn't get in the way :)
That would have been me, although I attributed it to Ray Kroc (McDonalds) and was corrected.
I came to this thread to simply say "persistence", and had a wry smile seeing this at the top.
Of all the thousands of pithy statements I've read over the years, that one has stuck around and served me well for over two decades, probably three now.
That's a great quote! It ties nicely with others of the same theme. One of my other favorites is:
"There is no failure except in no longer trying. There is no defeat except from within, no really insurmountable barrier save our own inherent weakness of purpose." -- Elbert Hubbard
“Nothing in this world can take the place of persistence. Talent will not; nothing is more common than unsuccessful people with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent. The slogan "press on" has solved and always will solve the problems of the human race"
