No longer at the peak of my photography skill

Bebu, I'm being a bit metaphorical and, therefore, perhaps a bit oblique. It's not all that important in the end.

I used to teach a photography class in the evenings at a local high school. It was mostly moms and the title was always something like "How to Take Better Pictures of Your Kids and Family". One of the first things that I told them was always, "You're going to be much less happy with your pictures once we start this class." My intent was to give then an understanding that once they started to learn more about photography, they would realize that their pictures were not very good. Then they could learn how to improve them.

 

Is it possible that you are judging your photography a little more harshly now? Ansel Adams used to be happy with a few really good pictures in a year. If you are being critical, I think it's a bit much to expect one keeper in a day of shooting.

Some good suggestions here to help you get your Mojo back, but if it never comes, don’t fret. Think of all the things that you have become better at as the years have passed.
