If you think you can do it, you can.

It's always too early to quit.

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

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

Be gentle to all and stern with yourself.

Without hard work, nothing grows but weeds.

Quality is not an act, it is a habit.

Leap, and the net will appear.
