But then I am not made to become "great", anyway ...
If thats what you think, that is what will happen.

One of the defining traits of any "great" person in any art is their unshakeable belief in themselves. That belief along with the opinions of your peers define you as such.
When I was in music, on a daily basis, EVERYONE told me how good I was, that I was destined for greatness. Over time, I began to believe it, and in 12 world class competitions, I won 12 first place trophies because in my mind, there was no one better, hence, I worked harder than everyone to make sure of this. It is this singular focus that pushes one from one plateau to another... but at that level, one has to be careful not to fall off that very high mountain that everyone places you on, becuase it hurts.
My photography is currently only for me, and no one else, hence no one else's opinion of if I am good or bad really matters. What makes a great photographer? The opinion of your peers and not much else.
Many call Ansel Adams a great photographer, but if you look at his work, it is not technically perfect, it is often not asthetically perfect, but it is often damn good. He of himself did not think of himself as a "great photographer", people and his peers made him great, his death, made him immortal.
How you present yourself to the world, and how the world reacts to your presentation of you, defines greatness. This is why some of the greatest artists have to this day never even become known... due to their lack of self-esteem. Ironic that it happens this way so often, becuase talent should be the yard-stick upon which we are measured, not attitude, esteem or opinions of other less knowledgeable in our field.
