My dad was an amateur photographer for a while, and even got one of his photos published in the newspaper.

He said nothing improves a landscape picture more than having a person in the picture. I didn't believe him.

Later, I went on a trip to Hawaii, and took maybe 300 landscape pictures of its beauty. Upon looking at them at home, I realized he was right. The ones with people in them, even random strangers, were always more interesting.
