The question I ask myself like almost every day is, 'Am I doing the most important thing I could be doing?'

The market is always right, but it doesn't always reflect the true value of a company.

世界上充满了显而易见的事物，但没有人注意到它们。

成功的衡量标准不仅仅是利润，还有积极的影响。

Never put off till tomorrow what you can do the day after tomorrow.

We've done price elasticity studies, and the answer is always that we should raise prices. We don't do that, because we believe -- and we have to take this as an article of faith -- that by keeping our prices very, very low, we earn trust with customers over time, and that that actually does maximize free cash flow over the long term.
