Harvey Mackay: Discipline is critical to success

The determination of departing Denver Broncos quarterback Peyton Manning to win Super Bowl 50 against the favored Carolina Panthers was riveting. It reminded me of a quote he gave earlier in his career: "Being there every week for my teammates is really important to me. It's about accountability."

That's discipline, and it's rooted in little things. Isn't everything? Little things sow the seeds. The harvest comes when you can discipline yourself to routinely face life's toughest complications and frustrations. That's a crystal-clear window on the success of the oldest quarterback in Super Bowl history and the only starting quarterback to win with two different teams.

Denver's discipline shone in both directions. Wade Phillips, coordinator of the Broncos' imposing defensive machine, is the son of Bum Phillips — former head coach of the Houston Oilers and the New Orleans Saints. According to Bum: "The only discipline that lasts is self-discipline."

Whenever I eyeball the résumé of someone applying for a management job, I look for evidence of self-discipline: As candidates have prepared themselves for past jobs, did they identify and master at least three to five key self-disciplines essential to future success?

Did the candidates stick to their routines — even their daily exercise program — after suffering a career setback? Self-discipliners bounce back the fastest.

Does a prospective manager grasp that the self-disciplines needed by the people around her or him probably differ from the ones that bosses ­master themselves?

Uncommonly strong self-discipline is a hallmark of success in any era. Elon Musk, who's worth a comfy $12 billion-plus, tops today's list for innovative business thinkers. He will turn 45 later this year. After co-founding PayPal, Musk masterminded the product architecture of Tesla Motors, founded SpaceX and provided the initial concept and financial capital for Solar City. Tesla Motors' battery technology has electrified the industry. SpaceX is redefining space travel with reusable launch components, and may one day colonize Mars.

• These days, everyone is hot to develop abs of steel. Fitness training technologies have evolved like every other discipline. It pays to learn them. If you spend valuable time working up a sweat, best practices produce the premier payoff.

Roy Neuberger, who lived to be 107, made several fortunes, and thereby endowed numerous art museums. At 94, he paid a personal trainer $45 three times a week to help him through a 45-minute workout. At a buck a minute, it helped keep Neuberger spry enough to collect his National Medal of the Arts at the White House at age 104.

• You may bust your buttons with pride about how regularly you stay in touch with your network, but are you using the cutting edge of social media to do so? Or are you still sending pals press clippings when everyone else is routing them links?

• I have readers hooked on audiobooks: a great habit to make. If you listen on airplanes, do you also use noise-canceling headphones? A number of ear doctors point out that these more expensive headsets allow lower-volume playback.

Be choosy about the number of self-disciplines you adopt. You don't want to morph into a robot. Focus on doing a few well.
