I think I understand the main idea behind this post: that you learn from either your own mistakes or from someone else's mistakes. However, I don't fully agree with the idea that everyone is either like their parents OR the opposite.
A person's beliefs/behaviors is simply a result of their own ability/judgement to learn what's good for them vs what's not. For instance, I am always very punctual and manage time well as if it were ingrained in my DNA but my sister is the complete opposite of that. Maybe I, at some point in my life, learned that I need to be punctual and always on top of my chores to be successful while my sister figured there's other things that are more important for her to succeed in life? I don't know.. I guess, it's really us figuring out whether or not developing a certain trait or habit is worth our time and/or will be helpful in your future.
It's interesting to see how it worked out for you though! I always find it amusing how siblings can be so different despite a common upbringing. If you have any siblings, where do they stand regarding this topic? It would be interesting to see the differences or the common grounds..
Now I'm over here figuring out what all I learned vs what all I decided to erase from living with my parents for so many years :)
