My sister and I basically copied what our parents did. I got a degree in engineering like my dad (but pivoted to data science), and my sister got a degree in elementary education like my mom. She works much harder than me but earns significantly less and frequently comments about how massive of a mistake it was to go into teaching. I'm not really sure what the lesson is here other than that the world isn't fair. From my perspective, my sister is generating much more value for the world than I am, and yet all of her efforts result in very little reward. I'm mixed on what to tell my future children. I want them to do what they love (or what they feel is important), but that may result in a very difficult future financially. I suppose I'll just try to make the trade-offs in career choices as clear as possible and hope they make decisions they won't regret later.
