My wife and I were born and educated in the Denver area. We owned a home in the area with a mortgage way less than thr rents were talking about here. We tried to live in the area while progressing my career but there are real limitations. Once we moved to the bay area my career totally blossomed. It was indeed a lifestyle change.
Back to the topic at hand, giving OP advice. He didn't post asking for advice on better cost of living, etc. He asked for advice on moving to SF. There is no substitute for your career than spending your younger years in a crucible like the bay area. It's good advice for them to move there while they're young and can take advantage of the connections made and knowledge learned for a lifetime.
