Thanks. :) From where I'm sitting the skills that are mostly going to be in demand in the future are those which are very practical, rather than the more esoteric stuff. People are going to want things fixed, basic systems maintained and suchlike. When money gets tight, make and mend becomes much more important.
I'm a guy who has made his living from being handy with computers. I studied something esoteric - Sociology. I loved the major, I loved the statistics, I loved the field - but no one hires a dude with a sociology degree. So I leveraged skills I had built along the way in computers. Now I'm super far removed from hands on computer work, or sociology, but I don't regret either set of skills. I'm not telling you to give up your dreams - you should study what you like, make a go of it - but along the way, learning how to be a plumber is a valuable skillset that has steady market value.
