I see your point, but I don't think goldie is a great example (what did she really sacrifice). But I was a little too generalistic and OTT with the stage mum comment.

It is a fine line to tread between support and sacrifice. I look at it from the point of view of someone with two kids. I could never condone uprooting the family for a dream unless it was in the best interests of BOTH my children (not just the one who has the dream) as well as my husband and myself. It is not about sacrifice then, but rather compromise and realism.
