Just based on 401 K alone, if I retire at 65, with 4.5% growth figured in, I will easily hit my number. That is not taking into account my pension or my wife's 401K.
So yeah, my number is totally hittable by 50 or 55 if I wanted to retire.
I also have $$ from inheritance, and so does my wife. My kids will have money from us and their grandparents too. That is how our families role. Our great grandparents came over from Italy, Ireland, and Poland with nothing, and they made sure the family would never want for anything again. It is our responsibility to continue that. I know that will get the self made crowd in an uproar, but I am not afraid to admit it.
