If you think you can do it, you can.
You never know what motivates you.
The dog that trots about finds a bone.
If you can dream it, you can do it.
By failing to prepare, you are preparing to fail.
To know oneself, one should assert oneself.
Well done is better than well said.
Know or listen to those who know.
Be gentle to all and stern with yourself.
Problems are not stop signs, they are guidelines.
Belief and knowledge are considered to be two different things. But they are not.
