I disagree. Everyone has the potential to be their best self (flaws included). Sometimes we need a little guidance or reminding (even the most well-intended) to stay the course. So, you can understand why someone does something and still be angry about it. Lack of self-awareness does not imply inculpability.
In your quiet moments, what do you think about? How far you’ve come, or how far you have to go? Your strengths, or your weaknesses? The best that might happen, or the worst that might come to be? In your quiet moments, pay attention to your thoughts. Because maybe, just maybe, the only thing that needs to shift in order for you to experience more happiness, more love, and more vitality, is your way of thinking. - via: http://www.marcandangel.com/2012/06/08/60-quotes-change-the-way-you-think/
