A photograph fills different needs, at different times in life. There are ideas and understandings that people can never fully experience without photography. It's not merely the camera you are focusing—you are focusing yourself. Then, when you touch the button, what is inside of you comes out. It's the most basic form of creativity. Part of you is now permanent.
The joy a photojournalist gets out of his work must be in the act of taking the photograph, solving the problem of the moment. You have to take pride in the actual picture when you're shooting it. To do this, you must be aware of everything around you; you must keep educating yourself as widely as possible; you must come up with ideas; you must keep abreast of the current market; you must keep well grounded in current techniques.
