The phrase “my business is my pension” is one I hear quite often from business owners and I get it. It takes a lot of sacrifice, both mentally and physically, to build your own business and also a lot of personal expense.
It can mean pouring all your finances into your business in the hope that one day it has enough value to it that you can sell it and ride off into the sunset. For some they may decide to keep the business and take a backseat in the future while still maintaining an income.
As hard as it is you should never rely solely on your business to provide for your retirement. You would be taking a massive risk that could mean you end up not only losing the business you built, but losing your retirement too.
