You have to learn to ignore them - that's what I do. I pop them in potting soil mixed with equal parts clean sand, water them good when I first plant them, then water them about once a month indoors (unless it's really dry) or once a week (or so) if they are outside in summer in pots. That first picture was just a tiny stub about 2 inches tall that had broken off a plant, that I stuck in my metal chiminea (I have a coir liner and sandy soil in it for succulents in the summer). I pretty much ignored it all summer, and then just replanted it back indoors, and it's more than twice it's size. They are wonderful plants, because they love neglect.
