I think that's nonsense. I just talked to the newbies for about half an hour about the house. Not since then. Apparently, the impression arises that I constantly pressure and lecture them. I don't even talk to them. Zero. Not a single word since then.
I'm only doing this for fun for myself. What they do then will be a surprise and then we'll throw everything on the table and stir vigorously.
Apart from that, we definitely can't afford more than one house. Honestly, how many here just build 2-3 houses? I think very few! So we're happy if we manage one and we don't even consider ourselves the poorest.
That's why mistakes would be shitty – you'd regret them your whole life.
My daddy, for example, built his first house at 18. One corner didn't quite end up 90 degrees when he was laying bricks. He still has nightmares about it and it reduces the value of the house. That's crap. It doesn't have to be that way.
