I find that one camera one lens namely the ones I have in my hands work best for me. This not to say that I don't have additional lens in my bag but rather that I simply don't spend a lot of time question my choice of lens. Be it right or wrong I simply live it, even in situations where I think one of my other lens will give me better results I'll often walk/explore the scene with the lens I have on the camera to see what shots I can find and only afterwards will I switch and shoot with the other lens. Some people handle the question of not having the right lens at the right time by using/carrying one lens, I handle it by not worrying about it.
Trying to see something new whither I'm visiting someplace new or a place that I've visited many a time before.
