对你的产品发誓。如果你不这样做，其他人也不会这样做。
Swear by your product. If you don't, no one else will.
"The markets are always changing, and so should your strategies."
诗歌是灵魂的音乐，在心灵的寂静中回响。
The study of the mind must be based on direct observation.
The more you're in the state of flow, the more you'll develop skills, the more you'll achieve, and the more you'll feel good about yourself.
