For me it's time. And physical limitations - if I notice that the muscles in my hand ache I usually take it easier to avoid overdoing it. I try to control my eagerness to learn NOW, and instead try a smarter approach where I listen to my hand. Although, I have to say that my legato practice has really improved my endurance, my fretting hand gets a lot less tired and is more relaxed that it used to be.

@Jon Bjork I could probably add another thing that I guess I was aware of but didn't articulate, and that perhaps some of you can relate to: frustration. At times I wish I was better att seeing the glass as half full instead of half empty. It's a bit like a since-curve: first it's exciting when learning something new, then it turns into frustration, then once passed that stage it's back to exciting again. It's a part of my learning process that I don't like very much, so I'm working on focusing more on the glass half-full aspect of it all.

Holy crap! That's amazing playing. I had a bit of a similar feeling as last Friday when I saw Yuja Wang live for the first time. If you haven't checked her out, I recommend looking her up. Her skill on the piano is mind blowing.

It's a bit bright on my TV, apart from that it looks fine to me.

@Markus Weber-Frede enjoy! I'm convinced it'll be a great show :)
