and inspiring thread. Like you, I've radically simplified my life and aspire to do so further in a small community that encourages a peaceable self-sustaining, cooperative life style.
I do think earning an income below the taxable level is not for everyone, but my children are no longer dependent on me and I have the luxury of age few talk about: no responsibilities beyond living in good will, a peaceable, virtuous, responsible life.
My only real regret sometimes is that I cannot donate to good causes as much as they deserve; but I do volunteer time, energy, art, etc. whenever I can. to offset that regret, I am free and clear of any support of Empire wars and tyranny. For me that is personal peace.
