I think the thing with advice like “Stay Focused” is that one has to specify, “Focused on WHAT?”
Staying focused means nothing until you address that question.
As for Elon Musk, for me personally, I’ve gotten completely turned off what he does. And for one central reason: He’s SO “go here, go there” without any rhyme or reason”. He’s a very rich man who wants to follow his whims. From going to space, to selling flame throwers, he may be the example of what happens when there’s a complete lack of focus and disciplined thinking. Blake Gossard
