Director Sujoy Ghosh can prepare himself for any kind of turmoil, but can't come to terms with getting up early on weekends

"With time life toughens you up. You realise that you are capable of much more than you thought... but not waking up early on a Sunday, " Ghosh, who rose to fame with 2012 movie "Kahaani", wrote on Twitter.

He is likely to come up with a sequel to Vidya Balan starrer "Kahaani".
