Much like two snowflakes are never the same, it's a similar story for coaching styles.
Take Cardinals coach Bruce Arians and ASU coach Todd Graham, for example. Both coach right here in the desert, both certainly know how to win, but they handle success and adversity much, much differently.
Let's start with Coach Arians. His team is out to a 3-0 start. They've scored more points in the first three weeks than any Cardinals team in history.
But what did Arians have to say during Monday's press conference?
"It wasn't perfect by any stretch of the imagination," he said after the Cardinals' 47-7 stomping of the 49ers on Sunday. "We left a lot of yards out there offensively. We had some bad penalties that cost us close to a hundred yards of offense. So, there are a lot of things to correct."
The guy is insatiable. Literally one of the greatest starts in franchise history, and he finds things to critique.
Now to Todd Graham. The Sun Devils were two days removed from one of their worst losses since Graham arrived in Tempe. What did he have to say on Monday?
"Obviously (we did) lots of positive things ... as a matter of fact, I thought we did a lot of really good things," Graham said after ASU was dismantled 42-14 by USC at Sun Devil Stadium.
"I feel good about how we've gotten takeaways defensively. I don't think we've fallen off any there. I think it had more to do with the opponent, and that's the biggest thing. There's not much to talk about."
It's safe to say: We have two very different coaching styles here in the Valley.
So, what's the better attitude to have: never satisfied, or the eternal optimist? I guess the only ones who can answer that question are the players.
