Regarding cameras, it's harder (and more expensive) to wrangle with gear acquisition syndrome (GAS) but after switching from Canon EOS to Fuji, because the Canon stuff was too heavy when hiking, I managed to restrain myself most of the time. Because the question always is whether my images would become better with different gear or with more trial and error.
I opted for trial and error and eagerly watch a selected number of YouTube channels who almost always show me that I should and can improve myself and not my gear.
