Why do you enjoy it? That's more important. It's far more common to attribute this trait to 5s rather than 4s by the way, out of a need to "recharge".[/QUOTE]
The why has a lot to do with substance abuse. The drugs keep me company!
I feel like I'm subverted by the 3 wing. I keep trying to appease others and put forth a flashy image, that while useful on a shallow level ends up stabbing me in the back. I think true 4w3's will realize this endless split personality torture that we deal with. Sure, we can convince others with our silver tongue, but we are betraying them because we're employing a superficial charisma that is empowered by the 4's uncanny intuition.
To stay on topic, 3w4's are far less risky than 4w3's. The 3 will succeed admirably through sheer charm and purity of purpose to "sell" himself. He is flawless in this regard. 4w3's will bring a certain uncertainty that can either thrill his audience, or scare them. And I think 4w3's have a harsher *split* in their personalities that is palpable if one gets to know them well.
