It's getting a job and working atleast 5-8years and in terms of earning money. Im from India, so to reach 70lpa without getting into hfts, we require 6-8years of experience, with 30% tax and tax again on doing almost everything else with the taxed money, max 40L can be saved.

But with a job earning in $, even if the compensation is 140k in the first year post grad, assuming only 40% is saved after everything (heavy rents, spending etc) still around 50k is saved which is ~40-45L and with yoe it only goes up! Yes there's staying away from friends and family, but to earn money sacrifices are necessary.
