Set loose, a child would run down the paths, scramble up the rocks, lie on the earth. Grown-ups more often let their minds do the running, scrambling, and lying, but the emotion is shared. It feels good to be here.

Most adults have a vocabulary of around 60,000 words, meaning that children must learn 10 to 20 words a day between the ages of eight months and 18 years. And yet the most frequent 100 words account for 60% of all conversations. The most common 4000 words account for 98% of conversation.

There is redemption in sadness. It tells me that for nearly five months in 2003, I lived life with the open, raw, refreshing outlook of the young. The payoff, though difficult to quantify, is much greater than I expected. I have no regrets about having gone -- it was the right thing to do. I think about it every day. Sometimes I can hardly believe it happened. I just quit -- and I was on a monumental trip. I didn't suffer financial ruin, my wife didn't leave me, the world didn't stop spinning. I do think of how regrettable it would have been had I ignored the pull that I felt to hike the trail. A wealth of memories could have been lost before they had even occurred if I had dismissed as a whim my inkling to hike. It is disturbing how tenuous our potential is due to our fervent defense of the comfortable norm.

If you seek revenge, it means you're scared or you feel guilty for what happened in some way. It's okay to be angry with someone, but don't think about revenge. It's like a disease that eats you up.

As a result of my hike, I am much more inclined to "do" things. I will have fewer "should have done"s even if it means incurring some "wish I hadn't"s.
