Too busy with a bunch of crap to do anything interesting till the summer.

One thing I'm still working on is improving my swimming. I find different sports (also video games) as test areas for self improvement - the results are generally very obvious, and I think you can improve your calibration. Specifically the surprising thing about swimming is how far the 'natural' path (doing a lot of practice) is from optimal, at least that is the impression you get after watching one of the Total Immersion lectures. And the funny thing is that the end result of the TI technique looks way more natural and easy than the 'natural' swimmers'. I wonder how many areas this extends to.
