１。 如果是关系不错 的朋友，互相经常帮忙，可以帮着做。
２。如果是对方有潜在的价值，比如将来有可能用得着的地方，可以帮着做，但一定要让对方明白你是帮了他一个大忙，让他知道欠你一个人情，以备未来之需。

You probably won't die on the position you are at today, and more often than not, the circle of the industry is not as big as you may think. Build your reputation, expand your circles of friends, have greater influence.

2) Flexibility: In a large corporation, first line managers are not that different from employees. They deal the same shit as you do. Keep them informed about your decision and show enough respects. Leverage them. But at the end of the day, you rely on your own judgments, not theirs.

3) Is it a fun thing to do? To many, this could be the number 1 criteria whether to accept or reject the request...更多精彩文章及讨论，请光临枫下论坛 rolia.net
