"当你回顾我们大约七年前开始研发Kindle的时候……那时你只能下注。如果你下足够多的注，而且足够早地下注，它们中的任何一个都不会是孤注一掷。"

Simplified Meaning:

When companies develop new products, they often have to take risks without knowing if those products will succeed. Imagine a business trying to create something new like the Kindle years ago. The company had to decide to invest time and money in the idea even though it wasn't sure it would work. By taking these calculated risks frequently and early on, the company spreads out its chances of failure, so no single project will ruin the entire business. For example, if Apple bets on several small tech innovations rather than just one big product, it's less likely that one failure will hurt the company badly. People can apply this to their lives by trying new things and taking small risks regularly, like learning a new skill or starting a side project, rather than putting all their hopes on one big venture. This way, even if some things don't work out, overall progress is still made and the impact of any one failure is lessened.
