I am often contacted by people seeking advice, and in most cases, I am more than willing to provide a few words of feedback to help with a particular problem. In some situations, I will also ask someone in my network to provide insight, especially if it is a problem outside my area of expertise.
And there is one thing that never fails to surprise me. The majority of people requesting advice neglect to say please and even fewer say thank you.
Don't get me wrong: I'm not soliciting praise or demanding recognition. But, please and thank you are two phrases that constitute the bare minimum of politeness.
