I am pretty sure you may have days when you do not feel like picking up the camera. And
when you look back on your images, you do not enjoy them anymore. The sheer thought of making some more produces a cringe.
I certainly have days like these and still haven't found the best way out. Some argue that in such moments, one should put down the camera and focus on something else. Others suggest that, on the contrary, this is the moment to make photos and let the process of creation carry you away, pushing you up on the creative curve.
One or the other may work for you. But be sure to embrace the doubt and to own your frustration, as after every low comes a high. As always in life.
