In a world of billions of images you might feel empty and exhausted sometimes. When you working as a paid photographer you may experience a bit of pressure in a world where everything can be done cheaper and better by others every day. You can have the feeling of outselling your creativity for money with lots of competition.
To avoid that you can keep projects private without any commercial background. Something that only belongs to your taste. Maybe you don't need to work as a paid photographer and have a different job that pays the bills (or doing it only part time). There is no need to sell a single image like other people do. Try to listen to your inner voice and find the right combination that feels just right. Don't live the life of somebody else. Do it your way.
