I'm guessing if you're saying charisma and personality are the keys to success with a PhD in organic chemistry...well you've probably not met many with PhDs in Organic Chemistry.
Full disclosure-I spent a year working toward a PhD in organic synthesis before deciding that field wasn't for me(I ended switching over to analytical chemistry and couldn't have been happier). A lot of the reason, to be perfectly honest, was my advisor. He's not a big name many have likely heard of, although you'll find his name on some papers for reactions that are now staples in undergraduate O-Chem curriculum(PCC oxidation specifically). To be a little more direct, my first advisor had done a post doc at a big Boston school in a BIG lab headed by someone who would later win a Nobel prize, has multiple reactions named after him, and is otherwise one of the BIG guys in organic chemistry. He's also had more than a few accusations of...not pleasant...working conditions in his lab, and my advisor brought a lot of that with him.
I've had a half dozen or so Chemistry Nobel Laureates in the passenger seat of my car, some for quite a bit of time. Several were very pleasant, enjoyable people to be around, The late Bob Curl was the one that really stands out, although Marty Chalfie(who's a biologist, not a chemist-that was one of the first things out of his mouth when he called me to accept an invitation to our invited speaker series) might be a close second. There were some others I'd prefer to never interact with again, although I'll spare the names(not that anyone outside the field would necessarily recognize them).
That's all drifting pretty far, though. Most people find hobbies to occupy their time, and really someone enjoying playing video games is no different from Bob Curl who I mentioned above playing Contract Bridge competitively, something he did. For that matter, posting on Macrumors is a hobby for many people as well.
