Counting from one to ten is one thing... trying to get from the word ONE to the word TEN is another. By changing one letter at a time (and leaving the others in their original positions), I was able to form a "word bridge" to get from ONE to TEN in six steps. Can you do better? If so, post your response in the comments!
