I have never felt ashamed of talking about my own shortcomings, which is not to say that I am proud of them, just that I have never been ashamed of them.
You can feel vulnerable and accept it, but doing it for too long is likely to make one used to the situation, become lazy, start using it as an excuse, hence rises the risk of bigger troubles. You can work on your vulnerabilities to make yourself a stronger individual but then I guess one will have to get rid of the idea of embracing vulnerabilities.
One should not be in conflict, one can embrace this feeling for sometime and then work or oneself and then when better, embrace the feeling again. Just doing one thing or another might lead to extremism (posted a hub about this recently) or doing both at same time would lead to conflicting thought process.
