One of my favorite people, authors, really, who is a real-life example of an upbeat, contemplative person who really does
things to make this world a better, more peaceful place is David Albert. Oh, yes, and I believe he would be thought of as an unschooler.
His daughter Meera has a CD and has performed benefit concerts for causes she dearly believes in. David is a Quaker and is constantly working for the benefit of all humankind. He inspires me! Check out his updated site, his "good works" page
to see a little of what I am talking about.
As for being bothered by eternally sunny unschoolers, I do know I have come across a few people online who seem to gravitate to "always feeling good" or seeing unschooling as the path to "Nirvana", even to the point of stuffing feelings and problems; I choose to respect them in their journey towards finding meaning in their lives and I just enjoy the ups (and downs!) of the reality of my own life and my children's lives. IME, if I didn't have and fully experience the downs, the ups wouldn't feel so good! I also know that I only see a very small part of who someone is and what they believe in snatches, so I keep that in mind before dismissing them altogether (including the too-optimistic anyone's). I take from them what I feel rings true with me and leave the rest.
It's taken me a long emotional road to come to my own place of peace, and it saps my energy to think about whether or not I like or agree with someone else's viewpoint, especially when it's something as personal as an interpretation of unschooling for one's family. Don't know how clear that was...getting ready for bed. Yawn!
