Nothing in the world can not substitute for persistence. Talent will not replace it: there is nothing more normal than a talented loser. Genius, too, not replace it: the unrecognized genius is almost proverbial. Education is no substitute for perseverance: the world is full of educated derelicts. Only perseverance and determination are all-powerful. The slogan of "no surrender" decided, decides, and always will solve all human problems.
