These are great questions.
I was a 21 year old female college student living away from home for the first time in the university dorm. My major had not been declared at this point in the year, so I was exploring lots of options.
Back then thinking forward 30 years, I must have assumed that I would be in an established career, married with children and perhaps grandchildren! I really don't have super clear memory of what I was projecting forward into my future but this is what I will say for this post.
No, I did not become that person completely. If I were to list all of the ones that I'm not on this list I would actually be quite lacking in putting a check mark by each one saying yes I have become that, so I won't!
The main advice I would give my younger self is focus more on your schoolwork rather than on dating and choose your friends wisely. What you do now matters. Get close to God not religion.
Thanks again for these questions!
