I got into medical after my 12th but decided to chuck it as couldnt see myself cutting corpses.(also I am a little afraid of them

)Switched to commerce after a year and then decided to do an MBA.Got a couple of calls after CAT 04 but I think its better to do IAS for the following reasons-
1)You weild enormous powers.Something that even an IIT/IIM wont give you(your car doesn't get towed away)
2)You can start a business in your family member's name and rest assured you wont have any bureaucratic red-tapes for getting any clearances.
3)You can resign and opt for employment in private sector.Many IAS officers have done that.
4)You can do an MBA after being an IAS /IPS officer.IIM Ahmedabad will give you a call at 96%ile.(and they wont mess around too much with you during PI).
5)The syllabus for UPSC is damn intresting.Especially general studies.
6)you only live once .why not experience this as well?
But I think it is better to have MBA as a safety net just in case one doesn't clear UPSC,
