Time reveals who is full of shit. - Warren Buffett

Anyone who has become rich twice is dumb. Why would you risk what you need and have for what you don’t need? If you are already rich, there is no upside to taking on a lot more risk, but there is disgrace on the downside.

If you invested in a low-cost index fund — where you don't put the money in at one time, but average in over 10 years — you'll do better than 90% of people who start investing at the same time.

Financial staying power requires a company to maintain three strengths under all circumstances: (1) a large and reliable stream of earnings; (2) massive liquid assets; and (3) no significant near-term cash requirements. Ignoring that last necessity is what usually leads companies to experience unexpected problems.
