After I graduated from college, I didn't want to go to graduate school, and I didn't want to get a job, either. I was caught in a dilemma.
 in a dilemma between a rock and a hard place between the devil and the deep blue sea就是指每一個選擇都不好, 可是我又得選一個. in a dilemma 最普遍, 其它的也都是常用的片語, 在 between the devil and the deep blue sea 裡請注意, devil 不是指魔鬼, 而是指船邊連接的部分.
我大學畢業之後不想念碩士, 又不想工作, 真是進退兩難.
It gives the illsion that you've computed the entire answer immediately.
