Hill, 43, and hubby Tim McGraw have three daughters together - Gracie, Maggie and Audrey.
Speaking to Parade.com, she said: 'I constantly work at maintaining balance. For me, my family comes first. If my family is taken care of then everything else usually falls into place.
'My family and my friends are most important to me. These people are my foundation. And it's okay to take time for yourself.
'We give so much of ourselves to others and we need to be fuelled both physically and mentally. If we are in balance, it helps us in all our interactions.'
