Breaking Bad, Season 4

Gary:
It's like what they say: man plans and God laughs.

Walter:
That is such bullshit.

Gary:
Excuse me?

Walter:
Never give up control. Live life on your own terms.

Gary:
Yeah, no, I get what you're saying, but, uh, cancer is cancer.

Walter:
To hell with your cancer. I've been living with cancer for the better part of a year. Right from the start, it's a death sentence. That's what they keep telling me. Well, guess what? Every life comes with a death sentence, so every few months I come in here for my regular scan, knowing full well that one of these times - hell, maybe even today - I'm gonna hear some bad news. But until then, who's in charge? Me. That's how I live my life.
