What did I do wrong?

@renaissancedad @Firebolt1176 Thank you so much for all your contributions to this thread so far - I definitely agree that the hindsight and the advice in the thread is extremely useful! I was just wondering though what exactly you guys meant by packaging yourself well? Does that mean highlighting important parts of your application over and over again, for example, by writing about a particular extra-curricular in the Common App and Supplementary essays as well? How exactly do you package yourself correctly without seeming 1-dimensional (some other people have recommended using each opportunity to tell the colleges about a completely different aspect of your personality)? Thanks xx
