To know oneself, one should assert oneself.

It's always too early to quit.

Things do not happen. Things are made to happen.

Leap, and the net will appear.

By failing to prepare, you are preparing to fail.

What you do today can improve all your tomorrows.

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

Problems are not stop signs, they are guidelines.

Quality is not an act, it is a habit.
