it has always been noticeable to me that creativity in composition tends to be inversely related to format size. the larger the format, the more unadventurous or stiff the composition. I have seen this to be true even with the images from individual phtographers. Carrying the Galen example in the present day, there's a great deal of freedom afforded by image stabilized lenses, reduce noise at high ISO settings, improvement in smaller sensors...."
I agree to some degree that weight and bulk makes you move around less and thus opens you up to fewer creative possibilities because of the physical tiredness of lugging gear around.
So what I do is always have my camera and 50/1.4 with me basically 24/7 ...nice and light, I can take it to work, buying groceries, wherever. That way whenever I have a spark of creativity, anywhere, anytime, I can just give it a shot, and with the fast aperture I get a heck of a lot of flexibility for handheld tack-sharp images. Creativity is least restricted with this kind of light lens, and it's also a good lens for professional-quality results at the same time.
Then, if I decide based on the scene that I could do better, for example by changing focal length, using filters, bringing my tripod and shooting at lower ISO, macro gear, whatever, I'll make it a point to return to the scene (assuming it's possible) with all my gear, and redo all those creative sparks with better thought-out technique.
I do this on vacation as well; I set aside "photography re-do" days where all I do is go back out and re-do all the creative moments, possibly at different times, different lighting, different weather, etc.
