I sew a lot of times with no goals in mind. I like to try new blocks or techniques or color combinations so I just make blocks. Just blocks-very few end up in quilt, they're just stacked on a shelf. Some day maybe I'll put them together but right now they're just sitting there.
I don't think you always need a goal. Sometimes we just like to sew and it's good practice for when we do find that project. I've never made bags but you sound like you enjoy them and with each one you improve.
Just enjoy the sewing and have fun!
