Don't want to mind other people's business?

I think this sentence is very right, other people's business really do not want to manage, in fact, it is not good to manage. No matter how to say other people's business or other people's business, sometimes, people are their own business is not want to care, let alone other people's business, right? We often say that you do not have to care too much about the views of others, the same reason, in this issue, just because others do not care about your views, so you want to manage other people's affairs can not be managed. So you don't need to mind other people's business at all. Just mind your own. No one in this world lives for anyone but themselves.
