How hard do you drive your Z

[mike12002us]

I have a 2010 370z with 83k miles. I drive my car pretty hard daily but don't abuse it. I like to feel that rush of power, also people like to challenge me a lot. I make sure to take great care of my baby by keeping oil fresh and plugs are changed every 25k miles(overkill I know). Seeing as im getting close to 100k miles I'm not sure if I should start taking it a little easier on her. Im about to go get retuned at Z1 next month and going on the dyno pushing my car worries me a little. So what I want to know is how hard does everyone else drive their Z and at what point do you say I have too many miles to be pushing this hard?
