I know it's been talked about that Lance utilizes his anger to power forward... it was pretty evident in the crash of 03 when he hit the musette... that amount of adrenaline just gives you an extra surge...
I think (and this is just my opinion from what I've seen) that some people are very emotional and deal with them by letting them drive their responses to things... others tend to take those emotions more in stride... the driven people I see as very intense personalities and the "in stride" people I see as more laid back... of course this is just my psychobabble... my ex was one of the intense types... and is still learning how to use his emotions to drive forward in a positive way. I think both Eddy and Lance have focused that energy to be positive...
good gawd... hope that makes sense to someone besides me! LOL
There is a fine line between "hobby" and "mental illness".
