i got out of the IT biz for many of the same reasons that dave lists. although i had/have nothing top secret to bide.
i got tired of spotty income, clients that wanted a $2k system for under $100 and didn't want to do things properly. then, those same customers would freak the fk out when their $h!7 blew up.
in fact, the only "client" that EVER followed my advice with a computer build is glen. yup. true story. and, guess what? glen seems to happy with the results.... imagine that. (glen, it was and is my pleasure to have spec'ed that computer for you.)
anyway, dave, your woodworking stuff is the BIZ-DIGGITY. follow your heart.
the above is my two cents. anything else is extra.
