It's always too early to quit.

Things do not happen. Things are made to happen.

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

By failing to prepare, you are preparing to fail.

The secret of getting ahead is getting started.

What you do today can improve all your tomorrows.

To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

Without hard work, nothing grows but weeds.
