to be a little lawyerly corleone - good reasoning skills, the ability to think logically, and good writing skills are necessary conditions for being a good lawyer, not sufficient conditions. That you possess these traits in no way assures you would be a good lawyer. Also, my mother always tells me how handsome I am. However, as much as she may indeed believe it to be so I (and even my wife) know she's stretching the truth a bit on that one. Point being, those close and dear to you will say flattering things to you - take them w/ a grain of salt, not absolute proof of ability.
I'm not saying you won't be a good lawyer and won't do well in law school, but the "born and bred" argument does not seem persuasive. Honestly, not trying to be acrimonious, but your stated reasons were just too 'out there' to let pass uncontested.
