I don't think that's a good question. It implies that if she has reached her ceiling, she is done. With MCE/Gour, she reached a level she will never exceed again, but that doesn't mean there won't be more success. She is still very capable, in the right hands. If I thought she was done, I wouldn't be here but one thing she needs to realize if she seeks success outside MF/LB, is what Clint Eastwood said, " A man (woman) has to know his (her) limitations.
