到山顶有很长一段攀登路程，一旦你到达了，那里的景色将美不胜收。
It's a long climb up the hill but once you're up there the view is breathtaking.
对于走路你可能很抓狂，但你一旦到了顶层,你就是在第60层,你的重力势能,与你如何到达那里无关。
You might be winded doing it the second way, but when you get to the top and you are at the 60th story your gravitational potential is independent of how you got there.
但是，事实并未如此，你一旦到达了“那里”，你还是会感到不满足，从而将你对“那里”的视野转移到未来某个地方。
However, more often than not, once you arrive"there"you will still feel dissatisfied, and move your "there"vision to yet another point in the future.
