What is the "history" of your family is it like mine?
My sister can do no wrong, yet has no assests, no money, no super...get the picture.
I am the opposite, and yet I can do no right. Sad but I learned a long time ago that regardless of my achievements, in my parents eyes everything I do is wrong.
Go for it and look for positive reinforcements within yourself and like minded people who will praise your achievements.
My family history is exactly like yours but I have it from both sides! My sister can do no wrong and my hubbies brother can do no wrong. I find it amazing that I married a guy with a background so similar to mine. We have both just learned that this kind of favouritism cannot be beaten so we keep our mouths shut about what we do in our lives. We both know that if our parents ever found out what we have built for ourselves with hard work it will only backfire on us and expose alot of jealousy in our family. We will probably get accused of winning the lottery and not sharing our spoils with our siblings! It has made us better parents though. In no way would we blind ourselves to one of our children's faults in this way at the expense of the other. We support each equally and they are reaping the rewards of our sad history. Life has a wonderful way of making things right for the next generation.
