Are you so lucky to make a living with something that is a great fun and hobby or would you say, photography is hard work too? Every time I have a "shoot", especially with a new model, I find that I am totally drained and exhausted. I always feel a sense of urgency to not let those special moments of great expression or of waning light slip away and be lost forever, .. so I'm always running my brain at maximum speed to make sure I haven't overlooked any obvious flaws with the scene in frame before exposure. Lighting, expression, props, exposure, make-up, ..etc. It can get a bit much sometimes. I think it was Confucius who said: "Find a job you love,... and you'll never work another day in your life" !! I have been very fortunate in this regard. I have always loved my work. Electronics, Computers, Webpage design, ...and Photo/Artist.
