What is ENOUGH?

Everyone is putting up random numbers all across the internet about what a good salary in India is. I understand there is no one answer here. I understand it is gery contextual.

So here’s my question. Assuming you’re 25-30 and are mapping out your career. Everyone is dreaking of buying a house in a tier one city, living in a nice locality, driving a good car and travelling- atleast this is the dream sold.

What does one need to earn to make it? Not looking for - they should startup kind of answers, I understand that is the quicker route ( if everything goes your way)

What is a good trajectory
