You have to be there not for the fame and glory and recognition and being a page in a history book, but you have to be there because you believe your talent and ability can be applied effectively to operation of the spacecraft.
Whether you are an astronomer or a life scientist, geophysicist, or a pilot, you've got to be there because you believe you are good in your field, and you can contribute, not because you are going to get a lot of fame or whatever when you get back.
My kids are not known, and I think that is very important. So far they have lived a normal life, and will continue to do so. I feel they should have the possibility to live a free life without the burden of fame I have created.
