When I think about my hobbies, which include photography, cycling, motorcycling, hacking and fishkeeping, I sometimes think they’re quite diverse. After all, some of them usually take place outdoors, and others are very much indoor activities. They also seem like a diversion from the often overly cerebral world of clinical psychology. On further reflection however, there are parallels between all of them and psychology. In what might become a regular feature (at least until I run out of hobbies), I shall describe what I consider to be parallels between them and clinical psychology. The first hobby I shall consider is fishkeeping.
