If you can't you must, and if you must you can.
Whatever you are, be a good one.
Be happy, but never satisfied.
It always seems impossible until it's done.
Become a possibilitarian. No matter how dark things seem to be or actually are, raise your sights and see possibilities -- always see them, for they're always there.
I am not what happened to me, I am what I choose to become.
They alone live, who live for others.
The first rule is to keep an untroubled spirit. The second is to look things in the face and know them for what they are.
March on. Do not tarry. To go forward is to move toward perfection. March on, and fear not the thorns, or the sharp stones on life's path.
The limits of the possible can only be defined by going beyond them into the impossible.
Do not be afraid. Do not be satisfied with mediocrity. Put out into the deep and let down your nets for a catch.
I trust that everything happens for a reason, even if we are not wise enough to see it.
Neither worse then or better is a thing made by being praised.
If I find 10,000 ways something won't work, I haven't failed. I am not discouraged, because every wrong attempt discarded is another step forward.
I am not bound to win, but I am bound to be true. I am not bound to succeed, but I am bound to live by the light that I have. I must stand with anybody that stands right, and stand with him while he is right, and part with him when he goes wrong.
We do not consider our principles as dogmas contained in books said to come from heaven. We derive our inspiration, not from heaven, or the unseen world, but directly from life.
When I'm inspired, I get excited because I can't wait to see what I'll come up with next.
If you don't like the road you're walking, start paving another one.
The best way out is always through.
Write it on your heart that every day is the best day in the year.
Stop acting so small. You are the universe in ecstatic motion.
