These days I was watching an interview with a famous fashion entrepreneur and he said that no one is responsible for one's failure but her/himself. I am not sure if I agree with this specially because this type of speech may be something taught to very young children whose parents have great expectations about their children's career. If the idea is to instruct young entrepreneurs about reaching success, a better speech would be to accept failure first and then to use it as a brick to build up the brigde to success.
