Be kind whenever possible. It is always possible.
Never complain and never explain.
Begin to be now what you will be hereafter.
Be gentle to all and stern with yourself.
Only the educated are free.
If you think you can do it, you can.
Do not weep do not wax indignant. Understand.
Always desire to learn something useful.
Either you run the day or the day runs you.
The wise does at once what the fool does at last.
The role of the teacher is to create the conditions for invention rather than provide ready-made knowledge.
