Energize yourself to maintain focus throughout the day.

Imagine that it's 2:30 p.m., and that you've run into a brick wall at work. You can barely keep your eyes open, and you're struggling to stay focused. All you want to do is take a nap.

At times like this, you may make poor decisions or feel irritable, or you may struggle to deliver high-quality work or meet deadlines. And you may lack the energy to push ahead with new initiatives. Let's face it: to do our best, we need to be energized throughout the day!

In this article, we'll look at what lies behind low energy levels, and we'll explore what you can do to boost them.
