To know oneself, one should assert oneself.

Know or listen to those who know.

Without hard work, nothing grows but weeds.

Things do not happen. Things are made to happen.

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

Be gentle to all and stern with yourself.

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.
