It really is needed!!! Sometimes I get a little (a lot) frustrated when wines don't turn out quite the way I'd like them to. But, it's a lot of fun, and I enjoy seeing friends' faces when I give them my wine.
Sometimes my job forces me to run all the way up to the fourth floor via the stairway. I am on the 1st floor. I am usually worthless to anyone by the time I get there, 2 and 3 steps at a time.
