A photographer's learning curve

I'm seriously thinking about finding a mentor. I have been self-taught and always been a solo shooter in my entire photography life. I have learned as much as I can by myself. But...

I feel like my photography has plateaued and is not improving anymore. My subjects, styles and techniques start to fall within a narrow circle and all similar now.  Inspiration goes only so far. I need to step up to the next level. I can get some beautiful pictures with good techniques, but I feel like they are lacking emotion and creativity.  I want something greater.

I don't know what else I need to do to get out of this plateau. I need a mentor not in technical skills, but in creativity, artistic skills and subject-matter. I guess they are all hard to be taught, otherwise I would have read it.

Have you seen the famous 'A photographer's learning curve' ? 

Right now, I'm totally feeling like 'I suck', especially after finding the international, multi-award-winning burmese photographer Aung Pyae Soe on Facebook. I couldn't feel any smaller right now.  I always knew that there are many many amazing photographers not even remotely comparable to my skills, but they are not the ones I can relate myself to.  

There are two photographers I admire because I can relate myself to them in some ways. 

1) The first one  is the one my husband and I still call "The sophomore guy"(Pichaya Viwatrujirapong) because we met him when he was a sophomore at Berkeley while we were seniors. I've long been an admirer of his work. I can relate to him just because I knew him before he becomes famous with photography.  I really like his style. He's my idol. 

2) Now just added Aung Pyae Soe  to my list. I can relate to him just because he's Burmese; simple as that. And his work is amazing. I admire his creativity and artistic eyes, especially because I didn't get/see those kind pictures when I was in those places. 

I think it's worth to add that they are both of my generation. It adds to the term "someone I can relate to". There are plenty of people to admire if you don't consider the age. But the ones I truly admire are the ones that I could have been but I am not.
