While "taking up photography" might sound like a great idea now, but when you find out you need to wake before the sun and head out at dusk just to get the best lighting, you might not be as excited.

就拿“学习摄影”来说，这是个不错的主意，但是当你发现需要在日出前起床并得在昏暗的条件下工作只是为取得最好的采光，也许自己就不会那么兴奋了。

If you took the sun away, it would be like cutting the string that provides the pull and in that case what you would see is that the planets would just take off along a straight line.

如果现在移走太阳，这就像切断提供拉力的绳子，这样一来，你们将看到，所有行星，均沿直线飞出去。

大学就是一个缩小版的社会，所以同在一片蓝天下，我们都要学会与人交往。
