Michael Gilleland, who writes one of the blogs that I enjoy, wrote a post earlier in the week called "Pills to Purge Melancholy" that reproduced Sydney Smith's Letter to Georgiana Morpeth (February 16, 1820) which contains 20 tips to combat melancholy. The essay is full of good advice for instance: live as well as you dare, read amusing books, be as busy as you can, see as much as you can of those friends that like and respect you, and my personal favorite Be as much as you can in the open air without fatigue. Read Michael's post for all twenty.
Then later in the day, I read a post on SJ's Beat where she talked about some advice I gave her not very long ago (the advice included start a blog). We all have times when we need to get re-set. In the mountains, I am able to sort myself out. The hike up the mountain brings all the cares up to the surface and the wind at the top tosses them about and even blows some of them away, the hike down is when I figure out a new direction or how to deal with what's left. I loved reading the book Heidi when I was little and often when I hike in order to get emotionally strong again, I remember Clara going into the mountains to get well.
