Know or listen to those who know.
I can, therefore I am.
Begin to be now what you will be hereafter.
If you've got a talent, protect it.
Only the educated are free.
After a storm comes a calm.
Leap, and the net will appear.
Do not weep do not wax indignant. Understand.
Be gentle to all and stern with yourself.
Never complain and never explain.
I think this is what hooks one to gardening: it is the closest one can come to being present at creation.
Mistakes are the usual bridge between inexperience and wisdom.
