幸福的门户就在你内心。
The doorway to happiness opens from the inside.
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.
I believe that we are all capable of change. We can all grow and evolve.
