You can try to build a passive income stream around your hobby.
You can sell your pictures on shutterstock for example and collect money on them long after taking them. So basically you do the work once and thats it. Of course you need a lot of good ones to actually live off it but its worth a shot. Also passive income from youtube where you can share your technique or just creating styles for shirts that you can sell on other websites is a great way to make a living off photography.
I would advise you to build a passive income first and then see where your hobby leads you. So that you are truly free to decide upon your interests instead of your wallet.
