So you've burned the candle at both ends and now you're, well, burnt out. As Americans, we're continually working longer hours, not taking time-off, and for some, spending more time reviewing reports than catching rays on the weekends. In fact, according to their most recent study of nearly 9,700 full-time workers, EY, the global assurance, tax, transaction, and advisory services firm, found that one-third of employees report that managing their personal and professional lives has become more difficult. And an estimated 50% of managers said they work more than 40 hours per week.

But what do you do when your energy is lacking and you still have that presentation to finish, that dinner to make, or that memo to finalize? Below are some tips to keep you motivated and recharged so you can tackle your next goliath with fresh eyes and fresh momentum.

Take Breaks During the Workday: This seems simple enough, but I bet the majority of you still sit at your desks and eat lunch. We often associate working longer and harder leading to better results, but if we don't take regular breaks we won't be able to reenergize and stay focused in the long run. Make sure you're taking regular breaks during the day. Go for a walk, eat lunch away from your desk, stop by to say hi to a colleague, or simply take a few minutes to do so breathing exercises.

Put Down that Cell Phone: Today we can easily take work home with us thanks to our cell phones, tablets and other digital devices. There's literally no separation between work and home. Start having "off hours" from your digital devices on a daily basis. Try not checking your email until after you've showered, eaten or had your coffee in the morning. Put your cell phone away while eating dinner. These actions will pack a big punch in recharging your batteries and getting motivated to take on the day.

Rediscover Your Purpose: Why are you doing this job in the first place? Adam Grant, an organizational psychologist and professor at the Wharton School of the University of Pennsylvania, proved that understanding the impact of your work improves your performance and productivity. Your purpose is about having an on-going impact that is meaningful to you.

Ask yourself these questions to hone in on your purpose:

When was the last time you felt fulfilled, what was the specific impact you were having on someone or something that provided that fulfilling feeling?

Focus on those moments, and you'll start to see what kind of impact that is specifically meaningful to you. Once you know what kind of impact is important to you, you can start to create more of those impactful moments in your everyday life. By doing this you will feel immediately have access to endless motivation.
