Tapioca, like semolina, is one of those things that a school kitchen could have turned you off for life. I couldn't eat it for years, having been force-fed it at primary school aged six, with tinned jam, as it oozed like frogspawn out of the bowl and I wept and retched. For years I had the same malicious feeling toward beets and mashed potatoes, which were instant and came in lumpy granules. My teacher and I had a silent war every lunchtime; a war that eventually came to an end after my parents removed me from the school. Made to your own wont, in your own kitchen, tapioca is ambrosial, and worth being a grown-up for, as is semolina. This could also be a pudding, not a breakfast, just don't serve it with dog food–like tinned jam. Try a lovely homemade compote instead.
