Utter crap. If you want to be a better photographer, work at it.
Not sure about the "utter crap" part, but otherwise this is the truest thing said in the thread so far.
Getting better is work, and the more you put into it the more you get back out of it. Pay attention to what seems to work and what doesn't work. Lean into what does, move away from what doesn't. Find the tools that work for you. If one camera and one lens is what works for you in learning to be a better photographer, do it. If not, then find what does work for you. If you're not into rangefinders (not the case around here, obviously, but still relevant), try something else.
Learning to be a better photographer is a process that must remain very plastic. It must be adaptable. What works for you might be the worst possible way for me or the next guy, or it might be great. The only way to know is to try. And, as you try and as you explore various means and ideas, do make sure to get feedback along the way. Too many people toil alone in the dark and never get an outside opinion. Feedback is good.
Another oft-missed point in becoming a better photographer or better whatever in any creative area is to
feed your mind. Look at lots and lots of photography. Look at work you really like and try to understand why you like it. Look at work you don't like and try to understand why you don't like it. Listen to excellent music. Watch excellent films. Go to museums, read literature, etc. Feed your subconscious well and your exercises in improving your work will be more fruitful.
