Green Bay Packers coach Mike McCarthy no longer believes that the more time you spend at work, the better you are at your job.
McCarthy learned this the hard way, from first-hand experience.
Back in the day, McCarthy used to sleep at the office and spend countless hours watching film and going over game plans.
It took a while, but McCarthy learned that balance in his life and time management were critical to success.
"I didnít have balance in my life 10 years ago," McCarthy said during an interview this week in his office at Lambeau Field. "So I now try and do a better job of that, with family and then football.
"Iím a much better coach than I was because I couldnít shut it off. I was obsessed with it in my younger days."
McCarthy arrives at work earlier in the morning and said he tries "to go home at a better hour."
Waiting for him are his wife, Jessica, and four children still at home, including Jack, George, Gabrielle and Isabella -- ages 12, 10, 4 and 1.
"I tape my ankles now before I go home," he said with a smile. "Our house is extremely active."
McCarthy, who also has a college-age daughter, Alexandra, wouldnít want it any other way.
McCarthy said the kids help keep him young, or at least thinking young.
McCarthy can be found in the summer with other proud Green Bay area parents watching youth baseball games.
"I was at a baseball game last night, the Blue Jays over in Allouez, big win over the Aís," he said. "It was awesome. Itís great. (And) our little girls are so active."
During his years as an NFL assistant coach, McCarthy never appreciated life outside football.
"I slept on the coach, watched every tape that came through the video department, took all the notes, asked all the questions," McCarthy said. "Youíve got to keep doing that, but in the same breath, youíve got to look at your time management."
McCarthy said technology has increased his efficiency.
"The abundance of resources today is remarkable compared to what it was 10, 15 years ago," he said. "Your ability to have the information and to do the research is at your fingertips all the time, and we have a big talented staff, too."
McCarthy always harps on setting an upbeat tempo during practice, and he uses that same approach off the field. As his cell phone beeps with an appointment reminder, you get the impression McCarthy makes every minute of his working day count.
He gives credit to Matt Klein, football administration coordinator, and Lisa Waeghe, his executive assistant, for keeping him on track.
"Theyíre phenomenal in their organization skills," he said. "Weíre very organized."
McCarthy readily admits that being an NFL head coach is a difficult job. "Oh yeah, it will beat you up," he said.
But in the same breath, he adds: "Itís fun, though. I love it."
McCarthy has been doing this job for seven years, but rather than appearing beaten down, he seems eager to come to work every day.
"You get energized just driving by Lambeau Field, I know I do," McCarthy said. "I drive across (Highway) 172, I check out Lambeau. Imagine walking through the door every day."
Something longtime Packers equipment manager Red Batty said will always stick with McCarthy.
"When I got the job here, he said 'the pride is in the bricks' and it is," McCarthy said. "The bricks of this place is an energy source, it really is. Itís special. Iím not just saying it because Iíve got the job. But it is special. Iíve worked at other places Ö to be a part of it (here) is awesome."
The stoic figure many see at the podium during a McCarthy press conference is not the same person who in a one-on-one setting is relaxed, down to earth and a compelling storyteller.
If he chose to, McCarthy could get swallowed up worrying about all the things that could go wrong during the course of an NFL season. Instead, he has learned to focus on the things he can control at work.
At home, itís a little different story.
"I worry about things I shouldnít worry about, family stuff," he said. "I think all parents do. Iím getting better. Iíd like to think Iím a very aware person. My wife might say, she might disagree and say I worry too much."
But McCarthy has found that getting his mind off football sometimes isnít such a bad thing.
