Things I can't do right now but wish I could:
Other than flying and going invisible, I'd love to learn to read AND write traditional Chinese for many reasons. Most Chinese people I met understood Chinese, but when they talked to each other, they talk in Mandarin or Hokkien and for all I know they're plotting something against me right in front of me. Pretending to not know, but actually knowing how their language will surely be handy.
I wish I could swim. And I'm planning to learn swimming, just not after I graduate.
I wish I could learn all the programming languages and talk to computers with ease.
