What’s one thing you wish schools actually taught instead of memorizing everything?

I was thinking about this today.

We spend years learning formulas and facts, but nobody really teaches us things like:

• Managing money
• Filing taxes
• Basic investing
• Communication skills
• Mental health
• Interviews
• Negotiating salaries

If you could replace one school subject with a life skill, what would you choose?

I'm curious to see what everyone thinks.
