Another common thing of human behaviour is the inability to admit weaknesses. Funny thing is, it's one of the most common questions asked in an interview for just about any position. Funny thing is is that most people use this question as an excuse to remask one of their strengths as a weakness, and just make themselves look better instead of actually admitting a weakness that they do have. Another thing is, people don't want to admit what they're bad at. Only problem is, is that once you admit what you are bad at you can work to improve yourself. It's the first step of just about every rehab program, and probably the biggest too, is admitting you have a problem. Of course, no one wants to accept, let alone admit that they aren't as good as they make themselves out to be. I mean, being proud of yourself is an essential part of your self esteem.
