My dream is to be a photographer. How can I realize my dream?

Go out for a walk, take photos when you see the scenery you like, take more photos when you have the opportunity, and wait for the best opportunity. Contribute as much as you can. At first, you don't have to invest in too big a company, just invest in some newspapers. After the photography technology is mature, the scope of submission will be gradually expanded. It's just that photography is difficult.
