Jealousy. Show me one single relationship, family, friend, or otherwise, that does not have it and I will show you the meaning of the word "apathy".
That I know nothing of envy or jealousy is a direct result of proactively denying possession, of things, ideas, or love. I believe in stewardship, not ownership, and I do my best as a caretaker. That I have broken things that were in my care is also true, and in those failures I have learned to hold things more lightly.
Let your community be small, with only a few people;
Keep tools in abundance, but do not depend upon them;
Appreciate your life and be content with your home;
Sail boats and ride horses, but don't go too far;
Keep weapons and armour, but do not employ them;
Let everyone read and write,
Eat well and make beautiful things.
Live peacefully and delight in your own society;
Dwell within cock-crow of your neighbours,
But maintain your independence from them.
