Émile Coué

If you persuade yourself that you can do a certain thing, provided this thing be possible, you will do it, however difficult it may be. If, on the contrary, you imagine that you cannot do the simplest thing in the world, it is impossible for you to do it, and molehills become for you unscalable mountains.

Henry David Thoreau

If one advances confidently in the direction of his dreams and endeavors to live the life which he has imagined, he will meet with success unexpected in common hours… If you have built castles in the air, your work need not be lost: that is where they should be. Now put foundations under them.

Cardinal James Gibbons

I have lived eighty-six years. I have watched men climb up to success, hundreds of them, and of all the elements that are important for success, the most important is faith. No great thing comes to any man unless he has courage.
