Ricardo, I agree with the start up suggestions, and add that you will get familiar much more quickly just shooting scores of images indoors or in a comfortable familiar environment - either of loved ones (who generally do not notice the tiny quiet device) or of furniture, clothing or wall hangings - pretty much anything with intricate detail. Try to get a feel for how the RX1 portrays depth and colour. There is almost nothing this camera cannot do justice to for its FL.
Don't fuss over even very high ISO, for learning purposes 12800 is a good upper limit. Find any garden or tree and experiment with shooting distances. Try the excellent macro setting on anything. FWIW, I use A mode, and balance ISO with shutter speed, but I am an EVF enthusiast so that mode is easy for me. Let the AF do its thing in its own good time, it will nearly always get there given a second, even in dark caves.
What you need is an habitual usage pattern, a set of procedures that quickly become second nature, and I would not confuse settling on these usage preferences with trying to shoot real photographs right off the bat. You will likely find that the rendering is easier to assess if you don't try to shoot masterpieces right off ;-)
Finally, f16 is such a waste I never use it. The ideal range is this: idealised (i.e. planned) bokeh and dof - f2-f4, best IQ for deep scenes f5.6-f11, f4 is 'least excellent'. You can find excellent image ideas in the RX1(r) image thread, which I strongly recommend taking a good look at. And if you don't already have one, a soft release is very worthwhile, we had a chat about them some pages back.
