Neuroplasticity (yet again)

It occurs to me that one of the cleanest evidences of neuroplasticity lies in any activity one does over and over. I'll give a quick example: When I draw, if I don't see a shape of line correctly, but I keep trying, and then go to sleep, well the next day I often see it!! That leg doesn't go there. Nor that ear. Etc. Another example might be rock climbing, which I love, when I can go. You may be bouldering and not getting up the boulder, but you keep trying. Next day, you solve the problem. This point of view makes my job fun, my life fun, it's a highly optimistic vision of a world where people keep trying, and keep growing.
