Some time ago I set an arbitrary savings goal of $1M -- I then decided I would not be "ready" to retire until I achieved this goal. There's no rhyme or reason to my choice other than $1M sounds like a "nice round number" and it has been tossed around by many as a "good number" for retirement purposes. How many others have doggedly pursued an arbitary number -- as I have -- without really crunching the numbers to find out whether that number is sufficient (or perhaps more than you really need)? Just curious.
