...especially, not enough water days before the climb, and, during the climb.
We used Wyler's lemonade and lemon drops to increase our sensation of thirst, so we would drink more water.
The problem I ran into was that I didn't have an extra bottle, and since the porters had to boil our water for 15 minutes, I ended up having to wait until morning to get my bottles back when I gave them to the porters at dinner. That meant that I was starting each day with a deficit... :-/
I sold my couch art by setting up a large format in or near a pricey neighborhood on a particularly photogenic partly cloudy day after rain on the weekend. I never seemed to have enough cards. I gave away every business card I had printed. Other artists, with more cash on hand than me, gave postcards with a sample of their work left over from "openings".
I need more cards.
I also have to make up some greeting cards -- the owner at the frame shop is interested in putting up greeting cards with my images on his shelves.
Intersection for the Arts, San Francisco, CA may tell you of similiar organizations in your region. Remember: two shows per year, even if "only" participating in a group show. They will very likely ask what shows have you had. Two shows, you are an artist. Get in shows. Shows at hospitals. Doctors have money. Shows in coffee shops in likely neighborhoods. People have money. City sponsored shows. Win a prize: get your work in the newspaper. I won a prize in an Art Show in San Francisco, CA in the Travel category.
Bellevue Arts and Crafts Fair, now called the Bellevue Arts Museum artsfair or Bellevue Festival of the Arts.
I will look into these.
I am getting shows, too -- I had my work on display at a coffee shop in Fremont from Thanksgiving through the end of January, at the framers' in February, and now at a coffee shop in Greenwood for March. I'm also going to see if there's an opening where I can show some images from my Africa trip at the Greenwood shop later in the year.
Large corporations and big local business and banks like landscape art photography on the walls in their lobby. Inquire right before "tax time". I think they find a way to write it off.
I have to start showing my work to local businesses -- I'm going to start probably with hospitals, and one of the new guys in our dojo is a chiropractor, and is willing to let me put some of my work up in his office also.
