I want to learn photography, but I can't afford it or a machine. Just reading. Almost 30 years old, more than one month 1000. Unrealistic, I can't support myself. ...

Don't be discouraged. Although you are 30 years old, you can have your own equipment (or use your own company's equipment) in a few years. As long as you study hard, persist in working again, endure the hardships that ordinary people don't want to eat, do things that ordinary people don't want to do, and master the skills that ordinary people don't have, your little wish to learn photography will surely come true.
