Remember the movie 12 Angry Men, or the Indianized version Ek Ruka Hua Faisla, where 11 of the 12 jurors hurriedly agreed that the convicted boy killed his father and, hence, should be awarded the punishment. Only one of them wasn't sure and in his response he asked all others to talk.
I saw this movie long time back, however, I got to understand the meaning of the whole movie around 10 days back. This, again, is with respect to my dilemma over choosing NUS or ISB for MBA. In this case, I was mimicking the 12th juror and wanted to talk about pros and cons of each institute and, finally, arrive at the conclusion. In the process, I talked to close to 15 people that really made me help taking a thoughtful/fantastically analyzed decision. And now almost everyone I talk to agrees with my reasoning. This was exactly the case in both movies as well.
Now, whenever I'll be confused, I just have to make sure that I go out, meet people and say: 'Lets Talk'.
