Jo March is a bit of a tomboy. She's a feisty, spirited young lady who'd happily grab a rifle and march off to battle with her father if only they'd let her. But in those days a woman's place was considered to be in the home, and that's where Jo must remain. Nevertheless, you can't keep someone like Jo down for long, and even in a home environment her sparkling personality finds full expression.
Jo is headstrong and independent, and that's putting it mildly. If she'd lived in Salem in the 17th century, she might have been called a witch, as she challenges society's standards of how a woman should behave. At a time when most marriages among the more respectable classes were arranged, Jo's unwillingness to get hitched to Laurie Laurence is almost scandalous. She's determined to make her own decisions in life, whether it's getting married or choosing to pursue a career as an author. Jo is a young lady with drive, determination, and bags of ambition.
As well as these positive characteristics, Jo also has her flaws. Speaking your mind's one thing, but she can be a little bit too outspoken at times. Sometimes she needs to curb that tongue of her's just a tad. But Jo's flaws are nothing out of the ordinary; they are all perfectly and recognizably human. This makes her a sympathetic character on the whole, one with whom we can more readily identify.
