Know or listen to those who know.

Begin to be now what you will be hereafter.

Never complain and never explain.

Things do not happen. Things are made to happen.

If you think you can do it, you can.

To know oneself, one should assert oneself.

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

If you're going through hell, keep going.

By failing to prepare, you are preparing to fail.
