Nothing like your loom (although I would love that!), but I'm the same way.
In addition to working 50 or more hours a week, I build furniture, garden, write for publication, quilt, a little bit of scrap-booking and stamping, make jewelry, and sew clothes.
Quilting and furniture making are the longest running as I started both while in junior high nearly 40 years ago.
ETA: Forgot reading! I love to read and fit that in by using audio books on my iPod and listening while driving.
