>>3070464So when you travel, you don't shoot any street? And if street bores you, then you're just going about it the wrong way. Street requires a lot of timing, pacing and a bit of luck. Gotta wait for something to happen or just present itself in a way that will make for a good photograph.
And to the original point, I kinda hear you OP. I got my FF camera with a 50mm and thought, "now i'm content". Soon after I started lusting for a wide angle, I got that and now i'm thinking of what telephoto I want to get.
Rather than enjoying what i have now and making the most of it until I get the other lens i want, I keep yearning for what i don't have. I put myself in check often, but here and there I think "if only I had that lens I could shoot this or that subject"
