People do “picture a day” challenges all the time. They last a month, or a year, and are usually boring. Then I saw a story about a guy that took one picture every day for 18 years. Some of them were really good, but I was mostly impressed by the scope of it, and that, whatever his ongoing motive was, once they were all assembled they presented a compelling and curated record of his life, the people in it, and his eventual death.

He took Polaroids, I have an iPhone with 30,000 pictures on it. So many pictures that most of them blur together and lose their context. So now I have this, with one a day.
