valuable idea. Criticism is and will be an indispensable part of both our academic and work life. Even after quitting PhD who knows whether you'll end up working in a book store inevitably bored to death all your life? But criticism can be used in a constructive way to roll your dice and build a better aptitude.

If you're communicative and outgoing, make friends easily and have convincing skills-- (which can also be acquired by experience) you can go for a medical representative job. Very trendy. And it demands the knowledge of science that you already have.

Confidence is the key. as long as your confidence is not faltering while you answer before your interviewer, you're alright! so, just say I love the fertile world of my subject. I want to dig deep indeed.that's why PhD.
