To me, fearless is not the absence of fear. It's not being completely unafraid. To me, fearless is having fears. Fearless is having doubts. Lots of them. To me, fearless is living in spite of those things, every single day.
对我来说，无畏不是没有恐惧，不是完全不害怕。对我来说，无畏是有恐惧，有怀疑，有很多怀疑。对我来说，无畏是每天依然生活下去。
成功来自于你关注长期，而不仅仅是季度业绩。

The most sustainable package is the one that gets reused and recycled endlessly.
