Do not weep do not wax indignant. Understand.
If you've got a talent, protect it.
Be gentle to all and stern with yourself.
Always desire to learn something useful.
It's always too early to quit.
Only the educated are free.
Begin to be now what you will be hereafter.
You never know what motivates you.
Without hard work, nothing grows but weeds.
Be kind whenever possible. It is always possible.
