I have, yes. Although born in a wealthy country, I grew up in abject poverty. I wasn't entirely unhappy then, and I do understand how social connection can help make it bearable. But I'm a lot happier now than then, and my happiness no longer depends upon the whims of other people, one of whom in particular betrayed my trust and left me deeply depressed for years. I greatly prefer my happiness being in my own hands, and I really couldn't go back to manual labour now, because there is so much I want to create and already not enough time to do it all; having more time to idly think about all the things I want to create and less time to create them would be torturous.
