Hm, I received the sort of upbringing you’re proposing, and I can definitely see where you’re coming from. However, my personal takeaway from my childhood is that hard work isn’t a virtue in and of itself, and as long as your goals are achieved it doesn’t matter how hard you work or not.
Of course, you could argue my parents didn’t teach me right. I’m pretty comfortable with where I’m at, but if you don’t want your kid to be like me, my outcome might be something to keep in mind :)
