My rule for my kids is that they can have anything else, but what they need to have at all times is a plan.
I don't care if their long term plan is to be a NASA scientist or a desk jockey or a farmer, they just gotta always have the next step for how they're making that happen at the very least conceptualized, and if they can't figure that out, they gotta look for something they can make a plan out of.
I want my kids to grow up happy, but they also gotta have a roof over their heads and I won't always be around for them to provide that.
But I believe failure and mistakes should be normalized so that it doesn’t become a devastation.
They might make a mistake and maybe you’re not around and they gotta live in a car for a week or two of or a stint, that is not the end of the world. That can just be a fire lit under the butt. It doesn’t mean fail, it can just be a moment in time between and it doesn’t mean the whole life is a bust.
Worst is if they let it get to them and decide the world is against all their plans. That’s how you get into a rut and stay there.
