As Djokovic concedes, having three brothers away from home, is hard for their mother Dijana.

"It's definitely heartbreaking for (her) to see all three sons go away and none of us live in Serbia ... but (my parents) understand this is the life we have chosen and they respect our decision," said the Australian Open finalist.

While Djokovic continues to turn his childhood dreams into spectacular reality, it's clear no matter where he finds himself in the world, his values and heart remain as close to home as ever.

"I try to stay humble as much as I can because I want to have the most important, most valuable people in my life around me like family and friends. They are the ones who actually keep me grounded and focused on what I do."
