I agree with all of the above.
As for piano -- what the ****? Kids love the arts -- all of them! The little guy will probably be working out his own "tunes" in pretty short order.
I remember Saturday afternoons during the summer when I was a boy. After finishing yard work and other weekend stuff, my dad could often be found at the piano with a can of beer, playing rhythm and blues and jazz. There was always music in the house. We kids played in school music programs. Our mom was a craftswoman and artist. And she took us to the library and encouraged us to read.
Play your cards right, you won't have to give anything up that means anything to you. If you have a little less time on your hands sometimes, just switch off the ****ing TV. The kid doesn't need it anyway....
