"Impossible is a word only to be found in the dictionary of fools."

"Faith is, at one and the same time, absolutely necessary and altogether impossible."

"Before you begin a thing, remind yourself that difficulties and delays quite impossible to foresee are ahead. If you could see them clearly, naturally you could do a great deal to get rid of them but you can't. You can only see one thing clearly and that is your goal. Form a mental vision of that and cling to it through thick and thin."

“So many of our dreams at first seem impossible, then they seem improbable, and then,
when we summon the will, they soon become inevitable.”
