personal responsibility

I think that personal responsibility is knowing that I am obligated to do something without anyone else having to tell me to do so. Or knowing when i am responsible for something whether its a bad or a good thing.  Personal responsibility can also be defined by knowing that I have to do something for MYSELF, for either my survival or my sanity. That is responsibility because i am responsible for myself.
i think that when something bad happens that involves me i have a gut feeling that tells me that i have to take on responsibility. for example, when my papa got sick and had to stay in the hospital. I knew in my heart that i was responsible for helping my grandma out. No one had to tell me that i had to take care of her, i did it because i knew it was my responsibility.
