Every challenge is an opportunity to learn and improve.
每一个挑战都是学习和改进的机会。
The more you know, the more you realize you don't know.
唯一失败的时候就是你停止尝试的时候。
The future is not a result of choices among alternative paths offered by the present, but a place that is created—created first in the mind and will, created next in activity.
The hardest part of returning to a truly wild environment is leaving behind the mechanical distractions of modern life.
Quality is remembered long after the price is forgotten.
幸福不是你为未来推迟的东西；它是你为现在设计的东西。
If you find serenity and happiness，they may be jealous；Be happy anyway。People really need help but may attack you if you do help them。
