Recently I was at my son's orchestra rehearsal and the conductor said something that resonated with me. He was talking to the kids about what to strive for. He said you should never strive to be good or to be excellent. He said you should always strive to be better. "Don't be good, be better. Don't be excellent, be better. Don't be great.... be better".
This has real application in photography. There are times when you might think you have seen everything and there is nothing else to learn. Believe me, I've met several photographers who are convinced they have "arrived". But we photographers we should always be learning and trying to grow as artists.
We should be seeking ways to "Be Better" not only in photography but in life.
