I go to extremes!

Call me a joker, call me a fool
Right at this moment I'm totally cool
Clear as a crystal, sharp as a knife
I feel like I'm in the prime of my life
Sometimes it feels like I'm going too fast
I don't know how long this feeling will last
Maybe it's only tonight

Darling I don't know why I got to extremes
Too high or too low there ain't no in-betweens
And if I stand or I fall
It's all or nothing at all
Darling I don't know why I go to extremes
