"Start planning for retirement now." My generation is not going to be able to retire (save for a lucky few that were born or married into wealthy families, or won the lottery, or something like that.) When you're living pretty much hand to mouth because the cost of living is so high and you have student loans...and it took much longer for your generation to become established in their careers, you don't think about retirement. Sure, it would be nice to quit work at 65 (or whatever the minimum age is/will be) and travel around the world or move to a beach condo in Florida or take up strange new hobbies or whatever it is people do when they retire, but realistically, that's just not going to happen. I'll be working until either a) I die or b) I develop Alzheimer's/dementia/some other health problem that forces me out of the workforce and into a nursing home.

"If it's your first marriage, you don't need a prenup, and if your fiance(e) asks you to sign one at that stage, it means that s/he doesn't really love you." This came from a book written before the economic downturn, and before the days when people were regularly coming out of college with tens (or hundreds) of thousands of dollars worth of debt. But that was then, and this is now, and with most people taking out hefty loans to go to school...and a divorce rate that's relatively high, that might not be such sound advice anymore. (Keep in mind that assets aren't the only things that get divvied up in the event of a divorce; debts do, too.) Wanting one certainly doesn't mean you don't love or trust your soon-to-be spouse, or that you want to get divorced or don't want to get married or have doubts about your relationship. It's just an acknowledgment that Shit Happens, and shit can happen to anybody. Kind of like having a fire extinguisher in the kitchen; nobody says that you're planning to have a house fire or anything like that. It's understood that you acknowledge that house fires can happen to even the best and most cautious of us, and while you hope you never have to use it, it's there if you do. I think of prenups the same way.
