Be gentle to all and stern with yourself.

What you do today can improve all your tomorrows.

If you can dream it, you can do it.

Begin to be now what you will be hereafter.

If you think you can do it, you can.

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

It's always too early to quit.

The secret of getting ahead is getting started.

To know oneself, one should assert oneself.
