To know oneself, one should assert oneself.
You never know what motivates you.
Problems are not stop signs, they are guidelines.
Always desire to learn something useful.
Do not weep do not wax indignant. Understand.
Without hard work, nothing grows but weeds.
Be gentle to all and stern with yourself.
Know or listen to those who know.
The wise does at once what the fool does at last.
If you can dream it, you can do it.
Our learning ought to be our lives' amendment, and the fruits of our private study ought to appear in our public behavior.
