When I was doing my undergraduate degree I got really into my statistics classes. It turned into both a career path and an obsession for me. All jobs I've had so far are related to data analysis and even when I get some spare time I am usually doing some kind of fun data analysis project. See my blog, if you want, which I've called "Data Until I Die!", detailing the various for-fun projects I've taken on and the analysis that I've done using R: Data Until I Die! | Data for Life .
