My PhD taught me how to think, and how to communicate complex ideas in a concise and unambiguous manner. The research and the subsequent thesis were mere by-products.
Agreed. I wouldn't want anybody to think that I don't think a PhD is a worthwhile thing to do, I am very proud of my PhD, my thesis and my research. Just in terms of a career it's a stepping stone and it has little value for someone to pretend that they have a PhD unless they use it to blag a job they are otherwise unqualified for.
I wish I could do another!
