Death - reading a crochet pattern is usually the hardest part, so I'd say you're doing very well! The nice things about granny squares: you can use up a lot of yarn scraps making them, there are tons of variations, it's not hard to lay them down then pick up where you left off, you can make clothing and so many things from them, they're small enough to be easily portable, and you can just keep increasing the sides until you have one giant, bed-sized quilt. The only down-side (from my perspective) is crocheting or sewing them together, then working in the yarn tails.
If traditional crochet pattern formats give you trouble, you might check out Japanese-style diagrams. The visual diagram is generally much easier to follow than the more traditional patterns. If you knit, you might try Tunisian crochet. The technique has several similarities to knitting and looks a lot like knitting when finished.
In any case, congratulations on mastering your first granny! Hope you'll be crocheting for decades to come!
