When you blame other people, you give away your power. You allow them to affect your environment, behaviour and well-being, the results you achieve, and how you feel. Blaming others is incredibly debilitating because it takes control away from you, making you feel powerless and helpless.
Taking personal responsibility is wonderfully freeing and empowering because you recognise that you decide how to feel, how to react to circumstances, and what you choose to do — or, indeed, not to do. On the flip side, realising that you have to deal with the consequences of your decisions, without the luxury of being able to blame circumstances or other people, can be really scary.
