Without hard work, nothing grows but weeds.

What you do today can improve all your tomorrows.

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

Quality is not an act, it is a habit.

By failing to prepare, you are preparing to fail.

Problems are not stop signs, they are guidelines.

The secret of getting ahead is getting started.

It's always too early to quit.
