Masood has been included in the Pakistan squad for the T20 World Cup and the home series against England.
Masood opened up about the tragic incident while addressing the media ahead of the seven-match T20I series against England, starting September 20 in Karachi.
"I have learnt a lot with time and have grown as a person and player. They are more important things in life than cricket so I just feel blessed to be doing what I do," Shan told reporters on Saturday (September 17) when asked if he was feeling any pressure on his comeback.
"My sister's passing away it made me look at things differently. I just feel now it is great to be getting a chance to play for your country or your favourite sport and earning from it but there is more to life than success and failure in cricket," he added.
Known as a specialist Test opener, Shan Masood earned his place in the T20I side on the back of his stunning exploits in the Pakistan Super League, the Vitality Blast in England and the National T20 Championship.
He said that he would not be blaming anyone if he fails while batting in the middle order against England.
"I just think you try to do your best when you get your opportunity and if you can't perform, only you are to be blamed. No one else. I will not blame anyone if I can't make a successful comeback. I can only do my best but result is not in my hands. As an athlete, you can never put blame on anyone for your failure. It is all about you."
Shan also spoke about the learning he received while playing in the English county season for Derbyshire.
"I played against and alongside some very good players and our coach, Mickey Arthur was a big help for me and helped me understand how I can challenge myself."
