The primary concern is if you need to leave your business before you retire with enough money saved up. I have some suggestions for solving this problem, but it’s not an easy one. One option is to retire now and work on something else. You could always start another business or get a part-time job until things are settled.
Another is to just let the business go. If you don’t plan on managing it anymore, you can sell it and at least recoup some of your investment. Or, if the company is fairly new and still growing, let someone else take over so they can start building equity in the company and keep things going until retirement.
