Shahid and Mira wed last year and recently welcomed their first baby, daughter Misha.
The "Haider" star said his wife has brought him closer to reality, something which was missing before marriage.
"There are so many things that Mira tells me, which are just so normal and I am still connected with that. I had probably forgotten 50 per cent of that, but she brings them right back at my life. Like, the price of petrol may be and how much I spend on online shopping," Shahid said.
The 35-year-old actor was speaking during a session at the ongoing 18th Jio MAMI International Film Festival with Star.

The actor revealed he takes Mira's suggestions during script narrations.
"She is 13 years younger than me so, she shows me the perspective of my audience... Sometimes when I read a script and can't relate to it, she looks at me and is like 'are you insane? This is exactly what normal people talk about. How can you not relate to this?'"
"It (fatherhood) gives me a lot of strength. I feel very strong, because I want to fight for Misha, be my best for her. That's inherently the feeling every morning. I want her to be proud of me.
