Between working toward your career goals and planning for your financial goals, it's easy to feel overwhelmed. But if you want to be more productive in 2018, you'll need to find ways to remain calm and focused.

A few simple changes incorporating the practices of some of the biggest names in business can help you turn things around and get ahead.

Here are four lifestyle changes that could help you become more successful in the new year:

1. Build a daily routine that inspires you

Tony Robbins , best-selling author and speaker, has helped many, including tennis champion Serena Williams and actor Hugh Jackman, feel more focused in their careers.

One of his favorite fear-reducing tactics, which he uses with clients and in his own life, is a strategy called priming . The process involves conditioning yourself to react to events in a certain way.

"If you're going to get the results that you deserve and that you want, you want to prime yourself for success," he said at an event in July . "You need a daily practice, a daily practice that's going to put you in the best state possible regularly."

To help prime yourself for feeling strong, Robbins recommends two steps:

First, he told CNBC Make It , set aside 10 minutes each morning for reflection and mindful breathing, a process that helps him stay focused and motivated every day.

Spend the first three minutes thinking about three things you're grateful for. Spend the next three minutes feeling at peace and thinking of people you care about. Finally, spend three minutes envisioning three things you want to accomplish.

Next, he suggests listening to an inspiring audiobook or podcast while you commute, do household tasks or exercise.

"Prime yourself for courage," he said, "rather than hoping you show up that way, based on the triggers of your environment."

2. Start carrying a book

Think about how many times a day you reach for your phone when you're bored or have down time. If you picked up a book instead, you could be benefiting more by learning about something new, reading something inspiring or simply relaxing with a fun novel.

Charlie Munger , vice chairman of Berkshire Hathaway BRK.A and business partner to legendary investor Warren Buffett, credits much of his success to a habit he and Buffett share — reading.

He says young people should spend less time on their phones and more time buried in books.

"In my whole life, I have known no wise people who didn't read all the time — none, zero," says Munger, according to David Clark, author of " The Tao of Charlie Munger ."
