I am going to comment on being tired, because I am doing a lot of strength building. I basically started with nothing but, I am building myself up for my trip. Strength is also important for taking photographs. Concentration can make you weak and tired. Building strength will make taking photos a little easier. I am mixing what i know from the past, like film and using it with current technology, like digital. Basically I'm mixing the past and the present. All my creativity is more free, despite my disability and limits. So there are no limits. One of the most important things is to be willing and confident. Remember that. Love B. Nice
