I would say that if you are truly interested and passionate about photography you will find your way back Like a ball bouncing back and forth in a funnel, you will get to the center.
Personally, if it were me I would say just pick something to shoot. Switch lenses, switch cameras, switch lights, switch whatever you want... but take a picture. Use your smartphone camera. Don't worry about the subject not being "artistic". Pick something simple that you think you know. A pencil. A rock. A napkin. A measuring tape. Just photograph it. If you feel like photographing it once then just do it once. But if you feel like you can take a picture from a different angle then do it. Study it. Go close, be far away. Suddenly that simple subject has become very interesting. You'll see the texture of the wood on the pencil end. You'll see the dirt stuck in the rock. You'll see things that may ignite your imagination!
I heard Paul Strand say that if seeing turns into looking then you're done. But if you see then you should shoot. (Or something like that!) I don't think you're done or you wouldn't be here asking this question.
I also heard something about Edward Steichen. He has shot WWI and WWII and he has shot the same cup and saucer 2000 times! Maybe you just need to find your cup and saucer!
