Positive Thinking Leads To Positive Results

I remember being angry with influential people stating we need to be responsible for the things that happen to us. It was a common things to say we needed to be grateful for all our experiences be they good or bad. This idea was first introduced to me when the movie The Secret first came out. I felt it was absurd to consider yourself responsible for  another's action against you, no matter what the circumstances.  I still do, however it does make sense to consider we are responsible for how we choose to respond to things that happen to us.  

Please share your thoughts on the matter. 
Do you feel we are responsible for everything that happens to us?
