If you think you can do it, you can.

If you're going through hell, keep going.

Know or listen to those who know.

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

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

By failing to prepare, you are preparing to fail.

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

Who seeks shall find.
