Part I — The story
The story
Michael Bloomberg built a financial-information empire around a single product so essential to Wall Street that customers can't do their jobs without it: the Bloomberg Terminal. After being fired from Salomon Brothers with a large payout, he bet it all on the idea that traders would pay handsomely for fast, reliable, all-in-one financial data — and he was right.
The terminal's moat is formidable: it combines data, analytics, news and a messaging network that traders live on, so leaving means losing your professional network as well as your tools. High switching costs and network effects let Bloomberg charge premium subscriptions for decades with little churn.
Bloomberg later served three terms as Mayor of New York City and became a major philanthropist. His company remains a case study in building an indispensable product protected by switching costs and a professional network effect.

In their words
The only way to get anything done is to just start doing it.
Being a leader means having the courage to make a decision.
You make your own luck.
