A bit more on refraining from complaining.
People volunteering to assist at est events agreed, among other things, to complain only to someone who could do something about it. Unhappy with how someone is handling something? Speak directly to him or her. It's a great way to approach life.
The Christ Church Unity folks I wrote about in the previous post call their project "A Complaint Free World." They'll give you bracelets and bumper stickers for free if you fill out their online order form (they'll welcome any donation you care to send in return, but they don't require it). They also sell t-shirts with this lovely Maya Angelou quote:
If you don't like something,
If you can't change it,
Change your attitude.
