I have break-throughs quite often - I don't know is it good or not.
Once I realized that "wow factor" on photographs matters mainly on the Internet;
Another time, that human being is almost always most important in photographs I appreciate;
Once that I can frame only in square, some time after that, that my alter ego sees the world mostly in panoramas;
Not long time ago I also realized that I don't want to share my thoughts on photography anymore (after doing that for almost 5 years on popular site in my country).
And I'm pretty sure I'll find other break-throughs soon. Every time I do, it changes something, and frankly speaking, I don't mind.
