IF WE WORK LIKE dogs for 40 years, we’ll get our reward, which is the chance to sit around and do nothing for 20 or 30 years. That’s the definition of a successful life, according to conventional financial wisdom. But it doesn’t sound like a whole lot of fun, does it?
My contention: It’s time to rethink the crazy distinction between work and retirement and, in the process, redefine what counts as a successful life.

RETIREMENT MAY BE our final financial goal—chronologically speaking—but we should always put it first. Partly, that’s because retirement is so much more expensive than, say, buying a house or putting the kids through college, so it takes many decades of saving and investing to amass enough for a comfortable retirement. But among financial goals, retirement is also unique in two other ways: It isn’t optional—and we can’t pay for it out of current income.
