What makes Branson's philosophy stick isn't recklessness—it's the recognition that analysis paralysis kills more dreams than actual failure ever could.

That distinction matters: the quote isn't an endorsement of thoughtlessness, but rather a corrective jab at the overthinking that disguises itself as prudence.
