ERD50, thanks for posting the links (I used to be able to do that, but don't know if if is possible via an IPad, or am too lazy to learn).
Mulligan, my father had similar discussions with my sister. She is intelligent, outgoing and multi-talented, and would almost certainly have done well in the business, IT or engineering careers he advocated. Instead, she was determined to follow her bliss as a musician. That ultimately went nowhere, but she enjoyed herself and has always been self-supporting through a variety of contract positions in various industries. While she leads much more of a hand-to-mouth existence than I would be comfortable with, she seems to be happy ... so it can work out. I hope for a similar result with your daughter.
"If at any times we must deal in extremes, then we prefer the quiet, good-natured hypocrite to the implacable, turbulent zealot of any kind. In plain terms, we are not so fond of any set of notions, as to think them more important than the peace of society". John Toland, The Description of Epsom (1711)
