"I find that with the right company, it's pretty simple to balance life and work. When I enjoy what I do, it doesn't feel like a chore. I am always sure that when at home, my family gets my attention first. I take time on the weekends to do things for myself and ensure that I regenerate before the work week begins."

"I make a strong effort to keep a healthy balance by spending my free time away from my cell phone and having more face-to-face time with my friends and family. Outside of work, I indulge in the things that make me happy. This includes hiking, camping, and woodworking. By consistently rejuvenating in this way, I can give even more energy when I am at work."
