That will only hurt you.", 'I understand that, I still like the guy, I am just sad I did not get those traits sometimes is all']
Just focus on what you do have, which I'm positive is a lot going for you!  You can also develop so many more good skills with focus and determination.  Just give it time and the hard work you're already doing.
