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

To know oneself, one should assert oneself.

To be a good loser is to learn how to win.

Be gentle to all and stern with yourself.

Problems are not stop signs, they are guidelines.

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

Things do not happen. Things are made to happen.

By failing to prepare, you are preparing to fail.

Know or listen to those who know.
