First, perseverance trumps talent. Second, do what you want to do, otherwise why bother? Third, be ethical; it might rub off on others. Fourth, don't give up.

Every picture should have a place you can go, a home, a climax.

Forget what it was. Look at what it is.

You are responsible for every part of your image, even the parts you’re not interested in.

The composition is already there, you just need to crop it

Each picture you take has power as long as it brings experience to the person who’s looking at it.

If you want to make more interesting pictures, become a more interesting person.
