I take pictures of people.
I would start with going out and finding people to photograph. Early afternoon I would go back home to work more on editing, post processing and take care of emails and marketing.
Drawing lessons really helped me to pay attention to the details.
Here's the first step for high school students
You should feel an attraction to images and story telling through them. Then you should start taking photos and see if you enjoy the process. If yes, then you should study photos from photographers you like and also study art and composition.
"You should be an architect."
I knew that I could never be anything else but a photographer so I went ahead and followed my path against my family's wishes. My passion and determination about my carrier choice was so strong that they were convinced by me and changed their minds. Now my family is proud of me and they admit they were wrong.
