I wish this were true, but its not even close. I wonder how your kids will react when they move away, and you're not around to police their emotional expression. If they're like me, they will promptly collapse into paralysis and self-destruction.
I strongly suggest that you frequently give your kids long stretches of time (months) to practice regulating themselves, without your interference.
And if they have anxiety or depression, please let them see a professional. If my parents had noticed the signs earlier, they would have saved me decades of pain.
As for when they grow up, adults who cannot manage their emotions get fired or are sent to jail. It is critical to be slow to anger, quick to forgive, and work at building strong friendships.
Imagine a millionaire who had millionaire parents lecturing his children on how they're not allowed to be poor. Lo! They're not! The lectures worked.
This sounds horrible. If I weren't depressed or anxious, being told that I wasn't ever permitted to be lazy or say that I was bored would make me so; and, if I were, then being told that I was lazy and hopeless would make it worse.
Seems like a really great way to have your kids feel guilty about the way they feel and then not talk to you about it.
Maybe they act like being hopeful because they are afraid of you. If you were my parent, chances are I would.

But while the sadness is real and shouldn't be ignored or suppressed, wallowing is unhelpful and you ought to move on with your life - just like if someone close to you dies, the deceased most likely would want you to be happy and continue living a good life and move on.
Others have responded to the depression/laziness part -- I was wondering if you could clarify what you mean by anxiety being caused by hopelessness? To my way of thinking hopelessness and depression have a lot of overlap, but anxiety not so much... It's more like a feeling of dread.
Fear of the dentist is common but understanding that the inconvenience is required for the desired outcome, the reason for the suffering, there is a hope to look to allowing the suffering to have meaning.
Do you really believe this, or do you believe your children aren't depressed? Your comment is not in accordance with science. Depression is a complex topic. I'm having trouble imagining a way to be more wrong. Is this satire?
While pizzafeelsright gets heavily downvoted, I think their may be some (dark) truth behind it: if you weren't lazy, you would sommit suicide instead of living a depressed life. :-(
I also have a feeling that there might be another (dark) truth behind the link between anxiety and hopelessness.
No offense, but teaching your kids this kind of nonsense is borderline abusive. It's so far away from so many people's experiences, and is just plain wrong. I hope you can recognize how damaging this could be for your kids down the road.
