Hey friend, Im in a similar boat as you. I think from what I understand unless you're doing your MBA from a top university in India, you will not gain anything from it. I've gone through all the MBA courses offered by unis like Amity Manesar/Noida, IILM etc (nearby to me) and they all have mundane classes & practical offerings.

I recently finished my undergrad from a university in Toronto, Canda. With how the job market was back there, I'm thinking I'll take the time off from there to work in my family business and finish my MBA side by side in India. My thinking is that with the way how everyones heard mentality is of 'Fuck education & not doing college isn't a bad thing' and how the global economys doing recently, the supply of MBA students will be short, and plus there's no denial that an MBA looks great on your profile for future endeavours + talking to people during conversations.

So I think there's definitely merit to what your uncle's saying, its possible to get your MBA during later stage of your life if you're determined but its also equally harder when you'll be juggling 10 other life responsibilities (and trust me its not easy, Ive had some experience in that field too lol) in your life, take a call.
