To know oneself, one should assert oneself.

Without hard work, nothing grows but weeds.

The secret of getting ahead is getting started.

The dog that trots about finds a bone.

Know or listen to those who know.

Well done is better than well said.

If you think you can do it, you can.

Begin to be now what you will be hereafter.

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