Hello Jennifer :) Awesome question.
I think a part of life is the journey of always finding ourselves.
I believe by a certain age/time [or even specific experiences in life] teach us certain things about ourselves that stick-but I feel the journey continues.
Like Lady Guinevere (the other commenter) feels/experienced; I believe that once we pull ourselves away from all the ideologies (preconceived notions, pressures, and expectations etc.) the world has of us-we can begin to find our way: our own way. But again, I think that journey is ongoing and we sort of..."collect" things we learn/experience while "discovering" our own self and identity.
