SANDRA Bullock says her selfish attitude is whats made her happy. The 'Speed actress - who is married to motocross enthusiast Jesse James - admits she has always put herself first and doesnt 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. Thats why I think I am happy. I do everything 100 percent - even my stupidest missteps. I know when Im getting ready to mess up, Im going to do it full-on. I look back at some things and go, 'I cant believe I did that. But I know I can make amends, and we can all laugh at it, because its my mistake. - ES 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 doesnt want to get taken advantage of. She added: I have to fight every single day to live my true life. I dont ever want to come home saying, 'I should have spoken my mind. I shouldnt have let someone say something that I didnt feel was right. - ES
