Hi Guys, I'm 67 and very happily retired and moderately comfortable in our finances. That being so, maybe I can offer a few suggestions of things that helped me get here.
First, whenever possible my wife and I maxed out my 401Ks. We also did all we could manage with "Roths," & standard IRAs. Some years only one of us could max. At that time we did whichever of us had the highest income to lessen the tax burden.
I never borrowed any money whose interest wasn't deductible. In other words I always kept a home improvement loan, a Small Business Loan or something else going on so every single penny I ever paid in interest was deductible. Before I owned a house almost all loan interest was deductible. But when they got taken off the list, I had to be "inventive." Every year I'd take the reduction in my taxes for deductions and use it to pay down the loan(s) faster.
NEVER EVER PAY THE MINIMUM PAYMENT ON ANY BILL IF YOU CAN AVOID IT!! THAT IS JUST DIGGING AN EVER DEEPER HOLE IN YOUR BUDGET AND RETIREMENT PLANS!
BTW: Don't get too obsessed with whether or not you'll get Social Security. After all the years I worked, over 42, & she worked 35, there still isn't enough income from Social Security to make a significant difference in our income.
