I'm not even really qualified to make this remark, as I have only read his first book and not followed life events closely since, but my vote is: "not for the duration".
Besides the driving to the sperm bank part in book #1 that has been posted about, I found a couple things striking in the read (relative to fatherhood)...
He says something like "all professional athletes are running from something... I never had a father, nor did I ever want/need one....".
DING THE BELL... wrong answer, Lance. Running from the lie in statement paraphared #2. There are no bigger lies in life than the ones we tell to ourselves.
So, my question would be to him... "Lance, when are you going to break the cycle buddy? No, I don't mean the term related to the sport either. I mean overcome your greatest fear and hurt in life (way beyound cancer) that you didn't have a dad, the pain it caused your mother, etc... you're so strong in so many other ways... are you afraid it ALL will fall apart if you do it (face it)... come on Lance, stick it out... be the father you never had and husband that should have been... DON'T BAIL!!!"
