Be gentle to all and stern with yourself.
The most effective way to do it, is to do it.
If you've got a talent, protect it.
If you think you can do it, you can.
Do not weep do not wax indignant. Understand.
Be kind whenever possible. It is always possible.
Know or listen to those who know.
Without hard work, nothing grows but weeds.
Only the educated are free.
If you can dream it, you can do it.
