Nope not me, can't be. It's easy to deny what you've done, said and feel to simply avoid accountability. Who wants to feel embarrassed and ashamed, raise your hand? I bet there are zero hands. I don't think there is anyone who is willing to feel any of that.
We all have faults because we are imperfectly perfect. In some way or another, whether directly or indirectly, we have all been at fault for a situation no matter big or small. Take for instance walking in the store, checking a text message and walked on the back of someone's shoe who was standing in an aisle. Who's at fault? A: The person standing in the aisle trying to decide which of whatever they need to buy, B: You who checked the text message while walking and bodied the back of their shoe OR C: Both? I guess this would depend on perspective, but I am willing to bet a $1 that most will choose B. The whole person that had to check a text message and didn't realize someone was in front of them. Now believe it or not, some people will choose otherwise.
To become a better person that makes better choices, it's important to hold self accountable. Hold self accountable for the things that you know are your fault. Hold self accountable for the things that you don't know is your fault but brought to your attention. Understanding what you can do better, will help you to achieve your absolute best. Failing to link self with accountability will cause you to miss out on growth.
Self analyze who you are to fully understand who you can be: A-C-C-O-U-N-T-A-B-I-L-I-T-Y. Stop being scared of facing what you've done to avoid dealing with what you need to change.
