sometimes it feels like my whole life is one giant career change...
most recently i went from being a customer service trainer for a major nat'l phone company to a technical support administrator and developer. didn't have a choice, they closed our call center.
making the change was scary b/c i was very good at what i used to do, whereas the new job was new territory for me and involved a lot of things i hadn't done before. it was definitely a good move, though, both financially and for my personal/professional growth.
