Actress Sandra Bullock says welcoming her adopted son Louis into her life has been a "game changer" and things have taken on a new importance.

"I see life from his perspective and you have a childhood. You have a childhood, no matter what kind you had, you have a child and I go guess what? This is the chance to have a childhood and remember it and be conscious in it and just enjoy it," Bullock was quoted as saying on American talk show "Today", reports femalefirst.co.uk.

"He makes me do stuff I wouldn't normally do and life becomes very important on a different level. My choices, what I do, I could fool around before but not now. It's a game changer," she added.

The 50-year-old actress said raising Louis has made her more conscious of the passing of time.

"And life goes so fast! I see the ticking clock and I'm like, 'It's so fast'," she said.

The "Miss Congeniality" star added that she finds it hard being away from her little boy.

"He's at home and not here and it's really hard. He's a beautiful soul."
