People who are dominated by the trait of responsibility feel psychologically accountable for what they have committed to do. They are internally bound by values such as honesty and loyalty.
The principle of pacta sunt servanda is not just a nice-sounding slogan. Once I commit to something, I feel emotionally obligated to see it through to the end. After all, my good name depends on it.
My obsessive conscientiousness translates into a reputation for being absolutely reliable, someone who can be approached first for help. I just need to learn how to select various ideas better, as I often take on more tasks than I should.
