Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

It's always too early to quit.

By failing to prepare, you are preparing to fail.

Either you run the day or the day runs you.

Wherever you are - be all there.

Begin to be now what you will be hereafter.

The most effective way to do it, is to do it.

You never know what motivates you.
