You never know what motivates you.
If you think you can do it, you can.
The wise does at once what the fool does at last.
Know or listen to those who know.
Be gentle to all and stern with yourself.
Do not weep do not wax indignant. Understand.
Only the educated are free.
It's always too early to quit.
Problems are not stop signs, they are guidelines.
Always desire to learn something useful.
If the individual is to be happy in the contemporary order, he must be open-minded with respect to new values and new arrangements.
