It's always too early to quit.
To be a good loser is to learn how to win.
If you can dream it, you can do it.
Know or listen to those who know.
The wise does at once what the fool does at last.
Problems are not stop signs, they are guidelines.
Be thine own palace, or the world's thy jail.
If you're going through hell, keep going.
What you do today can improve all your tomorrows.
Who seeks shall find.
Teaching man his relatively small sphere in the creation, it also encourages him by its lessons of the unity of Nature and shows him that his power of comprehension allies him with the great intelligence over-reaching all.
