Photograph because you love doing it, because you absolutely have to do it, because the chief reward is going to be the process of doing it. Other rewards — recognition, financial remuneration — come to so few and are so fleeting. And even if you are somewhat successful, there will almost inevitably be stretches of time when you will be ignored, have little income, or — often — both. Certainly there are many other easier ways to make a living in this society. Take photography on as a passion, not a career.
