I like listening to music of all sorts, home recording, knitting/crocheting, a little bit of yoga and pilates (and yes, I'm a man.)
I'm now trying to learn some computer skills. I learned C and Matlab as an engineering student and recently started learning HTML/CSS/JS (I wish I learned HTML earlier) and Common Lisp.
I know it will sound weird, but it's my big regret that I haven't really pushed harder to develop all the weird things I was interested in: Learning Chinese and French, making more penpals, playing the guitar, writing stories or essays, trying weaving and other kinds of crafts, etc etc. At least I get interested in a lot of things, which means you're not going to run out of things to talk about!
I loved Paris and Istanbul. I deadly wish I could have one more chance to visit Louvre since on my last visit I missed the whole French paintings section.
Istanbul was also great. Besides sightseeing, I purchased some yarn and cotton products, and I still remember being surprised at the quality...
Everything, anything! If you're interested in places in Korea to visit, I'll be more than happy to give you suggestions. Did I say I'm Korean?
