I think what he is trying to say is that it is obvious where you're passion regarding photography lies...in the street shooting. That said I don't think you should abandon all other forms of photography just yet or even perhaps ever! . You're still developing your skills and your eye and aiming your camera in many different directions at this point is only going to benefit you in the end.
You need to shoot but you can't get into the street 24/7 so take you're cam anywhere and everywhere you can or even point it at yourself

because it will all go to improving you as a photographer.
Many photogs end up shooting one thing and one thing only....maybe that will happen to you, maybe not....but I guarantee they all started out shooting a little bit of everything.
Go with the flow baby.
