There are certainly people who hold that position but I'm not one of them.

Me either. I wonder if someone's done a study to see if locus of control (internal vs. external) is a cohort effect due to the culture/spiritual teachings of the '60s, or simply age-related, so people who were in their 20's in the 1960's are now self-possessed and don't blame others for their feelings, while current 25-year-olds just haven't had time to learn it (although some may be ahead of the learning curve).
