People think being an artist must be a wonderful way to earn one's living. Of course, there are lots of great things about working for oneself, at home alone. What I really like is that nobody tells me what time to start in the morning, what to wear; or whether I can take the afternoon off and go to a football match.
But then, I have no one to chat with when I'm bored, no one to discuss last night's match with during the lunch-hour. Sure, I can spend the afternoon doing something I enjoy like swimming, walking the dog, or even sleeping, if I choose. But the work will still be there when I do finally get back home, and it's still got to be finished in time. Unfortunately, working at home means that people can always find me, whether I’m bored or not and once I’ve answered the doorbell, it's too late——my thoughts have been interrupted. No one would dream of calling if I worked in an office, but in an office I find myself making cups of coffee and listening to friends' troubles. As they talk, my ideas disappear and I feel increasingly stressed thinking of my work waiting to be done.
