I know a person who always said she's wanted to be a lawyer since she was 4-years-old. She got into law school right after her undergrad work, and would miss class at least once a week, always for things like "My boyfriend's sick and I need to take care of him". It didn't seem like she was taking it very seriously for a lifelong dream.
She just failed the Bar for the fourth time, and has pretty much gone into hiding, deleted her Facebook, isn't taking calls from anybody.
I hate to see anybody like that, but I can't help but remember how lightly she took law school.
