To know oneself, one should assert oneself.
The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
If you think you can do it, you can.
If you've got a talent, protect it.
I can, therefore I am.
Well done is better than well said.
Know or listen to those who know.
Who seeks shall find.
You never know what motivates you.
We must expect to fail... but fail in a learning posture, determined no to repeat the mistakes, and to maximize the benefits from what is learned in the process.
