This is complicated by resentment and, yes, even overt jealousy sometimes. Resentment because my DD's every success is evidence of how spectacularly my own parents failed to actually nurture me or give me what I needed as a gifted child, and sometimes, even toward DD who doesn't "appreciate" all that she has that I didn't. I'm also jealous of her. Maybe 'envious' is the better term, but when she turns into a passive, uninterested slug who doesn't care about any of the extraordinary opportunities she has... well, then I get pretty grumpy over it. She certainly lacks a lot of the drive and motivation that I had... which, yes, makes me even angrier at my own (long-gone) parents.
I don't know the details of your family life, but if they provided for you and did not mistreat you, that should count for a lot. Parents thiry or fourty years ago loved their children, but I think they typically had a more laissez-faire approach, trusting the schools to educate their children and not thinking they needed to be always be supervising or stimulating them.
