Since usually, experience and knowledge develops together with modesty and patience and the desire for positive influence; but not here, apparently.

Never worked for me -- I'm hopelessly impatient, though not such a monster of arrogance as some -- but I'd probably have learned quicker if I had been more patient.
My only view of 'more is more' is that it's a serious mistake to carry everything with you (if you have more than a minimal selection of gear) because you'll spend too much time worrying about kit and not enough time taking pictures.
Conversely, my view of 'less is more' is that while there's a big advantage in having tried a lot of kit, then cut down to what you're comfortable with, artificially limiting yourself by refusing access to extra gear is foolish. In other words, there's absolutely no merit in 'one camera, one lens' if you're constantly thinking about what else you want/need/would rather be using. You're back to worrying about kit again.
There's also the point that 'one camera, one lens' is a lot easier when it's the
right camera and lens -- for me, for example, M2 + 35 instead of M3 + 50 -- and besides, I'm much happier with 'two cameras, two lenses' around my neck plus two or three lenses in my pocket. On top of all that I can borrow Frances's lenses, and she uses different focal lengths from me. My choices: 15, [21], 35, [50], 75, [135]. Hers: 18, [28], 50, 90. Square brackets indicate rarer choices for particular applications, and don't include the Thambar and 65 Elmar.
