Art is possibly the most remedial and healing hobby in existence. And yet it can also be the means by which a man's sanity is abolished. An obsession, if you will, that parasitically torments the host, while simultaneously outputting marvelous work. The artist ultimately determines whether his tool - be it a paintbrush or a camera - is a flower or a handgun.
On a personal level, the camera is a hammer with which I chisel out a trophy of courage. In other words, I take photographs of things - animate and inanimate alike - that make me feel uncomfortable. I used to be tense and maladroit around people and in social settings. Now that I have been photographing people and social gatherings for 2 years, I can proudly say that I enjoy being with people more than anything, and have boldly conquered my trepidation. That's one significant reason for my exclusive interest in photography over other forms of art such as drawing or painting; from past experience I can say that many art mediums isolate the artist from community, from other people, while photography is capable of just the opposite.
Once one discovers this freeing aspect of photography, it truly becomes a lifestyle of sorts; it becomes a journey within the realms of your innermost being. If you are daunted by spiders, then grab a macro lens and a camera and shoot spiders, all different types, colors, shapes, and sizes. If you fear being alone in the dark, go outside at midnight with a camera and a tripod, and let the creative impulse cast out all fear. Just as the sensor of a camera absorbs light particles, it is also capable of enveloping the entities that frighten you most.
