To know oneself, one should assert oneself.

Know or listen to those who know.

Begin to be now what you will be hereafter.

You never know what motivates you.

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

Always desire to learn something useful.

The dog that trots about finds a bone.

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

If you think you can do it, you can.
