You never know what motivates you.

To know oneself, one should assert oneself.

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

Know or listen to those who know.

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

Be gentle to all and stern with yourself.

If you've got a talent, protect it.

The dog that trots about finds a bone.

Problems are not stop signs, they are guidelines.
