I've seen your posts rise to the top of HN many times. Who are you though? What is your occupation? Do you have any connection to startups?
His LinkedIn [2] says "Real Estate, Project Management, Technology, Philanthropy, Writing".
His youtube channel [3] is full of lectures about strategy.
Sooo..."life coach" mashed up with "strategy consultant" or something equivalent? Of course, you could ask, "Does it matter what his credentials are?"

It definitely does. Credentials are how I block the reality distortion field put up by a lot of enterprising individuals.
You might also be wondering about Sebastian Marshall. He's a friend of mine, an entrepreneur in his own right and wrote a book called Ikigai. More on him here: http://sebastianmarshall.com/about
"I signed up for a life a little bit off the mainstream path, so maybe I've got some interesting things for you. Writing on here is geared for those who want to cultivate their enterprising spirit, to build results, to become more creative, to gain a greater self-mastery, to get more perspective, to build more, to do more, to live more."
Yeah okay, but what's your day job and what have you done.
Occupation? Startups. Connection to startups? Ycombinator.
He's the real deal. ;)
