Vidya Balan is successful today. But only after a lot of hard work and struggle did she give hits like Lage Raho Munnabhai, Heyy Baby and Paa.

In one such incident before being selected for Vidhu Vinod Chopra's film Parineeti, Vidya went through 40 screen tests and 17 make-up shoots before the director finalised her as the heroine.

Vidya is all about grit and hard work. That’s her key to success.
