For a cheaper, albeit not quite as direct method, rise above the Arctic circle around the summer solstice and spend a night and see the sun above the horizon circle.
还有个虽然不是很直接但是比较便宜的方法就是在夏至左右，在北极圈起飞，花一个晚上看太阳从地平线升起。
Once you settle deeper, maybe you do not have to work hard to advance, but you can never see the sun rise.
一旦你沉淀下去了，也许你不用再为了前进而努力了，但是你却永远见不到阳光了。
