Michael Saylor, the founder of the world's largest corporate holder of Bitcoin, revealed in an interview with Natalie Brunell that he spent a decade trying to do "everything under the sun" at his firm, MicroStrategy. Despite these setbacks, Saylor remained optimistic and self-doubt, stating that he became successful when he understood the value of "focus". He then steered Microstrategy's corporate coffers into Bitcoin, rebranding it as "Strategy". His wealth has since risen to over $4 billion.
