Here is the text of Elizabeth Wagele's discussion of Type 7. The goal of this seventh type is to avoid the darker feelings that fueled Beethoven's creativity, such as suffering and loneliness. Beethoven himself had the Seven-ish trait of liking to play pranks on people. Wit, humor, and lightheartedness, the Adventurer's defenses, appear often in his music. Here's a Sonata where Beethoven clowns around.
Adventurers like to stay on top and live on the edge.
The virtue for Adventurers is sobriety. Since we don't learn how to deal with yearning and accept suffering and disappointment overnight, this sonata, that combines lightness and seriousness, is a good place to start. Moods and themes jump all over the keyboard. The virtue of sobriety has more appeal to the Seven when it alternates with playfulness, as this sonata does. While this sonata is a masterpiece, the goal of real live Adventurers is to be able to sustain sobriety and concentration for more than a few measures at a time.
