> It's her life

Clearly it's not. It's the life of those she copies and is influenced by. I strongly doubt any of the people like your sister are actually making actual decisions about their lives.

You absolutely should try getting through to her, because that's in her best long-term interest. She's literally destroying her life.

That's amusing. :D

Well ... go on, don't keep it to yourself.
