It may be different for those for whom photography is a career, or a living - the pressures of earning a living from what you shoot can sometimes zap the fun out of the process. For me, photography will always remain something I enjoy, as an artistic pursuit - though I do make some money from photography, it's not money I rely on, so I will never let it dictate what, when, or how I shoot. Since I'm a visually-oriented type, my inspiration comes similarly to Bjorn by simply heading outside with camera in hand...I always walk with a photographer's eye - I observe the smallest details, look for shapes, shadows, or lightplay, my eye goes to any motion - so it behooves me to bring a camera along since inspiration is fairly constant and random. There are certain subjects I love to shoot, and I always schedule time to pursue those - wildlife & birds, architecture, and night photography. The rest is just what strikes me. Some days, I just take a walk. Some days I get in my car and go for a drive. The camera is always there, and when walking I'll snap photos of various random odd sightings; while driving, I'll pull over to shoot something as inspiration strikes - a church, a scenic view, a bird on a pole, people walking...sometimes I even shoot WHILE I drive - street shots through the window, traffic at a light, a rainbow, streaking lights. Many times, those photos don't get posted - sometimes they're deleted - some work, some don't. But I enjoyed the process of looking for them, I enjoyed the inspiration to take them, I enjoyed the process of taking them, and that's the part that matters for me.
