"If your picture isn't good enough, you're not close enough."
Comfort is often a killer to creativity. If you're “comfortable” with your work you’re probably not pushing your limits. You're not learning, growing, developing, honing your edge. You may be getting very good shots but not necessarily the best you otherwise might get. If you really want to grow, as an artist and as a person you need to be uncomfortable, at least some of the time. You need to challenge yourself to be more audacious, take a risk, maybe even get a little reckless. It’s hard to overcome the fear of getting closer, engaging your subject, taking the braver shot but the more you do it the easier it will get.
