Shah Rukh Khan, who has three children -- sons Aryan and AbRam and daughter Suhana -- says parenthood is a journey that exposes one's "failings" and "fears".

"Parenthood is a journey through someone else's life into your own. It exposes your failings, fears, ability to love, hold on and most importantly, to let go," Shah Rukh posted on Twitter on Tuesday.

The 50-year-old is married to producer and interior designer Gauri Khan.

The actor will next be seen in 'Fan', in which he plays the double role of a superstar and his obsessed fan.
