Ok, I have to comment on this thread, with the completely opposite point of view. Sorry Mark, didn't mean to single you out.
I understand I have lived my life much differently than the majority of people on this board and have very, very few regrets. I was on one of my road trips with my close friend Bill, he is a doctor, and he has 2 military retirements, as well as 401k and property investments, and we were discussing SS retirement and when to collect. He is younger than me and he was adament that I would lose money if I waited to collect my SD until 70. Well, here is my not so unique circumstance,every year my SS goes up about 400 to 600 dollars, depending on my raises and salary. Why? Because I had little shown income when running a business, for obvious reasons, and I worked for the state for about 17 years at different positions and took the payout when I left each job, like a moron. But anyway, when I started my current position, 9 years ago, my monthly amount was barely 1k. If I wait til 70 and my pay does not change(which hopefully it keeps increasing), I will get 3k a month, much more manageable with my shop income source supplementing it. I had to finally share figures with him to drop the topic. He then saw my reasoning, and couple that with the fact I want to continue to work til I'm 75, all the while collecting SS and not being penalized for working, he saw tge lught. Not everyone worked a good paying job and stuck everything they could into retirement their entire lives. I am NOT complaining, I wouldn't trade my life with pretty much anyone's. But this is my reality and I own it.
