To know oneself, one should assert oneself.

The dog that trots about finds a bone.

If you can dream it, you can do it.

Know or listen to those who know.

Begin to be now what you will be hereafter.

Things do not happen. Things are made to happen.

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

It's always too early to quit.

Expect problems and eat them for breakfast.
