Instead of worrying about what people say of you, why not spend time trying to accomplish something they will admire

You shape your own destiny.

The unexamined life is not worth living.

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.

Always do what is right. It will gratify half of mankind and astound the other.

Once you learn to quit, it becomes a habit.

To attain the impossible, one must attempt the absurd.

I'm not telling you it's going to be easy - I'm telling you it's going to be worth it.

Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young.

Status quo, you know, is Latin for 'the mess we're in'.

Most people live and die with their music still unplayed. They never dare to try.

Our greatest glory is not in never falling but in rising every time we fall.

Make today worth remembering.

A man should look for what is, and not what he thinks should be.

We're lost, but we're making good time

It may have been in pieces, but I gave you the best of me.

The world is the great gymnasium where we come to make ourselves strong.

You say I started out with practically nothing, but that isn't correct. We all start with all there is, it's how we use it that makes things possible.

Once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been, and there you will always long to return.

There is a candle in your heart, ready to be kindled. There is a void in your soul, ready to be filled. You feel it, don’t you?

Perseverance is failing 19 times and succeeding the 20th.
