It's projects like this that keep me going throughout the night. When you find a cause you care about and take it to great lengths it truly pays off. I myself, haven't been much of a fan of smoking, the number of teenagers who start smoking and think it's easy to quit is somewhat unbearable over the years, but has declined, thanks to "The Truth". I was thankful enough to not care for cigarettes growing up. Being of cuban decent, cigars really run in our blood. After finding out my grandfather smoked cigars until his forties, it has made me more aware of the things that can endure on your body and to the others that are around the second hand. No matter what you smoke, it's smoke and it's wearing down your lungs.
Don't ever feel content, projects should fuel you and become never ending.
Personal projects fuel me to get out of my comfort zone every once in awhile. Comfort is a tough word for some of us, I believe it's the feeling to be content. Once someone feels content, it's hard for them to break out of that comfort zone. As a photographer, what I've learned early is that you should never be content in your work. There's always more to do to an image, a setting, a pre-visual, just about every area that includes a photograph.
