REtired after 31 years, wife retired after 25 years , both have pensions and draw SS and I have a part time hobby that puts us over 6 figures. Good investments, don't need any of it, as those are for my kids, and grandkids.
When you owe nothing to nobody, no home mortgage, no car payments, just monthly expenses, it's a nice comfortable life.
Being self employed even part time at 78, Self Employment Taxes suck, somewhere around 23%, if I didn't enjoy it I'd quit.
Still able to walk into my local Lincoln Dealership last March and wrote a check for over $67K, gave the blank check to the Salesperson to fill out, the lines on the check were to small to write that amount with my big writing style.
College Education, (both), one marriage, three kids (all college grads) good health, wise investing, good health and luck, life's been good to use..
