Most people waste time on people who are no good for them — in business or personal lives. What’s needed with a toxic or undesirable person is an exit strategy. Forget all the analysis about “why is the person the way he is” or pointless ruminations such as “Why me?” Find an exit, create it, and go through the door. Don’t waste time on relationships that will not and cannot work, that seem to matter now but won’t matter at all once you’re done.
