Every image made is part of a journey, whether it is your own or someone else's. Each part of that journey has highs and lows, but which ones stand out? What aspect of image making do you enjoy the most? Getting to the location? Taking the shot, and everything that goes into it? Is it the work that you can do to an image later on the computer?
The drive to a location, and the anticipation of what is before you can be a very exciting aspect of photography. The thrill of seeing what you have been seeking for a long time can be very rewarding. Maybe you've seen images of a location, and want to go to that place because you see an image that you would like to make in it.
Could it be that you make images because you have an idea of what you can do with it after the fact? Perhaps taking what you see and creating something out of that, or replicating a dream you had using elements of the real world? Post processing images is an art unto itself, those who enjoy it can be rewarded by the time and effort put into the process.
Whatever it is about photography that you enjoy, take time and figure out what it is. Just discovering the aspect of enjoyment is can enhance the experience.
