To anyone who has ever scolded me or who may do so in the future:
Before you try to offer me your opinion, be sure you are as wise as you think you are. I don’t need your help. Have you written six books? Hold three degrees? Lived in every major city in the US? Worked as a computer scientist, an investigator, a writer, a managing editor, a university instructor, a researcher, and a union laborer? Are you competent at virtually _everything_?
I am. I have. I do.
Sooner or later you will probably need my advice. If I choose to give it to you, it will _work_, if you can take the time to listen.
I, on the other hand, do not in all likelihood need _your_ advice.
Just bear it in mind.
