If you think you can do it, you can.

Be gentle to all and stern with yourself.

Things do not happen. Things are made to happen.

The wise does at once what the fool does at last.

Without hard work, nothing grows but weeds.

To know oneself, one should assert oneself.

Either you run the day or the day runs you.

By failing to prepare, you are preparing to fail.

It's always too early to quit.
