The value of drones lies not in flying, but in implementation.
只热爱实践而无理论的人,就像没有舵和罗盘的水手,永远不知道他可能漂流到哪里。
The perfect decks itself in beauty for the love of the Imperfect.
The right of nature... is the liberty each man hath, to use his own power, as he will himself, for the preservation of his own nature; that is to say, of his own life.
