"The right person will never force you to compromise your friends"

In this solo episode, host Jemma Sbeg reflects on what she would tell her 21-year-old self after spending her entire twenties documenting her life on this podcast. Listening back to early episodes from 2021—when she was about to move to Sydney, heartbroken, unemployed, and directionless—she realized how much she wished she could offer that younger version some perspective. The result is a list of lessons learned through mistakes she mostly would repeat, but a few she would not.

The relationships that shrink you versus the ones that expand you

The first and most urgent message Sbeg would deliver to her younger self: the right person will never force you to compromise your friends. She describes past relationships that did the opposite of what psychologists Arthur and Elaine Aron called "self-expansion theory"—the idea that love should incorporate the best aspects of another person into your own self-concept, resulting in deeper self-knowledge.

Show Notes

If I could sit down with my 21-year-old self, there are a few things I would definitely want to say. Today, I'm going to say them, like 'don't even THINK about moving in with that guy, use your savings account, care less about grades' and a few more. I also asked you guys, the listeners, about your biggest regrets from your early 20s so we can all learn from each other (how nice is that).

We discuss:

  • Why the right relationship should expand your life, not shrink it
  • Why you shouldn’t rush into adulthood
  • Financial avoidance and learning to actually save
  • Why audacity can matter just as much as hard work
  • Caring less about grades and more about experience
  • Why nobody can tell you exactly how to live your 20s
