To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

If you think you can do it, you can.

Without hard work, nothing grows but weeds.

It's always too early to quit.

By failing to prepare, you are preparing to fail.

The secret of getting ahead is getting started.

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

Leap, and the net will appear.
