 lot of bright guys, lot of bright students because of wrong choice of optionals because optionals is 500 months, that's a lot of months and optional irrespective of what you think requires about seven, eight months, part coaching, part self-study, there are new books to be read, GS is the leveling ground, everybody is same, like a more or less, but you come from different backgrounds, some science, some from humanities, some have done job and they come back, so optional I think is a very, very big challenge and you must make this choice very, very diligently and I can say that because myself and I started my preparation way back in 90s, I'm sure some of you are not born at that time, okay, so back then I also flirted with four five optionals, I think I started with mathematics because of my engineering background, then I realized mathematics of UPSC is very different from what I thought mathematics was, okay, so I left mathematics, then I took up physics, I had a lot for physics, in fact if it was not for UPSC and engineering that I took up, I was more inclined towards physics, I did one year of graduations for physics, then I qualified the examination and in engineering, so physics was my love and I took up physics, but then I realized that love is different and practical is different, okay, you should not always marry the person you love, okay, there's a different challenge altogether, so I realized physics and I studied almost six months, two, three months of mathematics I had done, two, three months of physics I had done, then I took up public administration because I thought I'll be an ice officer, I better know administration, okay, I killed myself over it, did whatever I could have, but nothing got into my head, okay, I again spent three, four months on that, then somebody told me sociology, my cousin, she qualified into service, she had sociology, there she said Shabhi takes sociology, I study sociology thankfully for only two, three weeks, okay, then I said I had no idea what to do, and then my mother told me one fine evening, she said, Shabhi why don't you try it, because she was seeing almost six months or seven months of juggling, struggling, nothing was happening, I'm studying and I have no clue what to do, then she told me why don't you take geography, I said this is an opportunity, why because my mother told me and I will take the subject, but doesn't mean I'll tell you this because of you, okay, so it was very convenient way, you know, we always spark our failures on somebody, so I said okay, I have got my inspiration now and I took geography, when people ask me why did you take geography, it was my mother who did it, and I thank her now that I think she saw something about me, I don't know why she said geography, it clicked with me, I didn't qualify, it was a different thing, but I think I love the subject eventually, so my suggestion to all of you is take your time.
