I personally prefer to take pictures of people, preferably people that I know. I almost never revisit photos I take of random things like landscapes or buildings. In the hands of a more skilled photographer those pictures might be valuable, but for me taking pictures of random things seems like a waste. Especially since I primarily shoot film, and every single picture I take costs money.

In twenty years which picture am I going to want to look at? A picture of a family member or a picture of a gas station?
