I love this! For a while I've had a book idea along the lines of Things People From My Type of Upbringing Need to Unlearn (but far better-sounding, of course). There are so many mistakes in those belief systems ... and the craziest part is that most are unintentional, and even well-intentioned.
Totally agree with what you're saying. I'll try to start experimenting with this idea. Excited to hear what you think.
