A family member gave me one of his old cameras, pic related, what should I do with it? I don't know shit about photography, I don't even take pics from my cellphone awful camera.

It's a Nikon D3200, the battery is a bit fucked, the baterry slot has no lid and the autofocus is not working, other than that I managed to fuck with it a little bit and kinda discovered what the configs do and how to take pics on manual.

Also, just got laid off and been NEETing for a few weeks being at home all day doing nothing, should I just go out and take pics of strangers on the streets? Is this what you guys do?
