Learned how to hold it correctly, do some chords, tune, clean it. My teacher said to balance between playing with my index finger and a pick, but I'm playing with my finger the time being, until I get my callouses togheter. Speaking of which, playing it doesn't really hurt my fingers at all. In fact, the thing that hurts the most are the positions of my left fingers when I hold it. I have to get used to that position, and it's the thing that's giving me the most trouble for now.
During chords sometimes my fingers will rest on another string, and I have trouble remembering to raise my finger and pressing hard on the string behind the fret.
It's pretty fun so far, and I don't really mind playing chords. I guess I have a lot of patience.
