I always heard that as well. Cinematographers love this phrase, but I totally agree. That saying leaves the concept less than dependent on personal experience. I still don’t understand why, but the purest of expressions seem to come as side effects of the engagement process; not as rewards for accomplishments. So, one must engage and be honest as they can with the act itself, which isn’t to say one must suffer, but just aim to be in touch with their own experience with the medium. I will admit I personally suffer, but it’s not helpful.
