Buying Freedom

IF 20-SOMETHINGS ASK me for financial advice, I suggest getting a job right out of college and saving like crazy, so they quickly get themselves on the fast track to financial freedom.
If 60-somethings ask me for advice, I advocate a phased retirement, seeking part-time work in their initial retirement years and, if they enjoy it, perhaps keeping it up into their 70s.
Yeah, I know, I sound like a real killjoy. My advice raises an obvious question: Is there ever a time when we should cut ourselves some slack and not have a job?
