Sandra Bullock says her selfish attitude is what's made her happy.

The 'Speed' actress — who is married to motocross enthusiast Jesse James — admits she has always put herself first and doesn't worry what anyone else thinks, even if they correctly advise her that her actions are wrong.

She said: "I never did anything according to what anyone else wanted. That's why I think I am happy. I do everything 100 percent — even my stupidest missteps. I know when I'm getting ready to mess up, I'm going to do it full-on.

"I look back at some things and go: 'I can't believe I did that. But I know I can make amends,' and we can all laugh at it, because it's my mistake. I try not to blame it on anyone else unless I fully know it was their fault — and then I have no problem pointing the finger."

Sandra also revealed she always speaks her mind because she doesn't want to get taken advantage of.

She added: "I have to fight every single day to live my true life. I don't ever want to come home saying: 'I should have spoken my mind. I shouldn't have let someone say something that I didn't feel was right'."
