Never complain and never explain.

By failing to prepare, you are preparing to fail.

Wherever you are - be all there.

If you can dream it, you can do it.

The wise does at once what the fool does at last.

It's always too early to quit.

Go for it now. The future is promised to no one.

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.
