What and who do you associate yourself with?
We can gain or lose credibility by who and what we are associated with. This is why we write resumes. People want to know who you have worked with. They want to be able to call your list of references. If your references are impressive then you will be too. This is true to other way too. This is happening in politics where people say if you voted for certain person then they don’t even want to talk to you. They don’t want to be associated.
