Shooting what you enjoy is essential to being a good photographer. I shoot a lot of things and I enjoy many hobbies.
Some people are super into cars and get into photography because of their car projects. Other people get into photography because of their pets. Many people get a camera because of family. These are all great reasons to get into photography.
I love nature and landscapes but I am big into sports and adventurous things. I try to shoot a little bit of everything that I like. This allows me flexibility to take pictures in many situations. The photo above was on a trip in the middle of nowhere. I decided to take a photo showing this great car sitting with the road stretching into the distance.
