I don't know that I am a old pro yet, but I started the 365 in October. At that point, I had stumbled across someone else's 365 blog when I was looking for inspiration for a very technical shoot I was doing. I realized that I use to be growing in my photography at a rapid pace, but somewhere over the years, I had become way to comfortable. I learned the art of photography on a Minolta 35mm but since switching to digital, I admit I didn't know every function of my camera (which is embarrassing). I saw this as an opportunity to make myself learn more. I expect a lot out of myself, so I knew I wouldn't want to take boring pictures for a whole year. So far, I've gotten so much more out of this than I ever expected. I see beauty and photos potential almost everywhere I look. Even if it's a day where you don't want to take a picture (I've had several), you still have to think..."how do I make window cleaner look interesting". I also set a rule for myself that I would only shoot in manual mode without a flash. I think I became too dependent on my presets. I also shoot with a 50mm because it wasn't my favorite lens when I got it. I've come to appreciate it much more. I've learned a great deal about myself through blogging as well as learning about others. I admit there are times when I'm annoyed by other's 365 blogs, but I remind myself that not everyone is doing it from a photographic point of view. Some people just want to document their lives with family and friends and that's a great goal as well. After I'm done, I hope to continue. If I had to change anything, I would have carried my camera everywhere from the beginning. I had a lot of "camera phone days" when I first started because I saw something and I didn't have my real camera with me. Now those days are reserved for times when I'm too sick to get out of bed
I also have gotten over the fear of breaking out my big camera anywhere I'm at. I was at a craft type store the other day and I took a picture of something they had for sale. I've realized that if you don't act like it's a big deal, no one else will. Finally, the 365 has gotten me out of the "oh there is a great picture....I'll come back and take it" mode. Most of the time, I would put off taking a picture because I didn't have time or a camera on me, but I wouldn't remember to go back or by the time I did, the subject had changed. Now I've learned to seize the moment more! Hope that answered some of your questions.
