It is so lovely watching him figure out what the world is about and how the everything works.
I hope that he continues to like to try on other people's shoes, especially the ones that aren't meant to fit.
I also hope that he holds onto that willingness to explore and learn out of his own motivation. I feel I lost it myself sometime in later high school. I think that there was so much pressure to do well and so little guidance to actually find out what you enjoy learning, perhaps have natural talent for, or given encouragement in areas that perhaps you weren't great at (I have never forgotten my year 8 art teacher looking over my shoulder at some sketching we were doing and exclaiming "Oh dear, art isn't really your thing is it"). With a but of luck maybe watching my little boy pick up lots of new tricks might encourage me to discover one or two of my own...
