A while back, in a different thread, I stated that DJ came across to me as a 'Stoner' type of person. His diction, mainly. Just had that sound of someone who rocks the ganj. But that was just an observation at the time which may have little to do with this.
But this, I think, does...and it's along the same observation I made about him back then. He comes across as a 'blow with the wind' kind of guy. The type who would easily go along with whatever is happening around him. I never sensed a strong type of 'this is my way of doing things' mien from him. More like, 'A party? Cool. Coke? Whatever.' He's like the anti-Tiger in terms of personality.
Now before I get hammered for totally talking out of my backside - I do have personal experience with addiction & substance abuse. I have been in rehab. And one of the things I learned is that there are certain personality traits common with addicts. It would appear DJ has these traits; at least from what I have gleaned from observing him.
And, if I may be so forward, this is also a life imitating art situation, as I wrote a novel last year about a pro golfer with a cocaine habit. In keeping with the rules of this site, I won't post links to it or promote it, and I'm really not trying to. But it does give insight into the addictive mind from the perspective of a pro golfer. If anyone is interested in learning more, drop me a PM.
