Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present.

Whatever you do will be insignificant, but it is very important that you do it.

Whether you think you can, or you think you can't - you're right.

Don't ever take a fence down until you know why it was put up.

I trust that everything happens for a reason, even if we are not wise enough to see it.

Out of your vulnerabilities will come your strength.

If you want creative workers, give them enough time to play.

The key to immortality is first living a life worth remembering.

Be happy, but never satisfied.

You are never too old to become younger!

It is only when the mind is free from the old that it meets everything anew, and in that there is joy.

If the only tool you have is a hammer, you tend to see every problem as a nail.

The starting point of all achievement is desire.

My advice to other disabled people would be, concentrate on things your disability doesn't prevent you doing well, and don't regret the things it interferes with. Don't be disabled in spirit as well as physically.

The men who have succeeded are men who have chosen one line and stuck to it.

If you spend too much time thinking about a thing, you'll never get it done.

Whatever you are, be a good one.

You need a little bit of insanity to do great things.

We are what our thoughts have made us; so take care about what you think. Words are secondary. Thoughts live; they travel far.

We all have possibilities we don't know about. We can do things we don't even dream we can do.
