What should i learn next?

Well I feel like i should learn something but I am not sure what i want to learn. I am in school right now but it doesn't seem enough and i want more out of it. I love different languages (I am fluent in sign language as well as English and my family knows different languages so i know parts of Spanish, Latin, Italian, German, Russian, Japanese, and French. Also one of my friends is going to start teaching me Chinese.) I get good grades in school as of right now. I am also learning how to sew (embroidery, hand sew, needle point, crochet, machine sewing, and quilting), how to do calligraphy (handwriting) and learning how to cook/ bake. I just feel like I need to learn more. Any ideas as to what to learn?
