However, the 55-year-old once shared that despite his success on the courts, fatherhood was ‘everything’ to him, telling the Belfast Telegraph,"Fatherhood is everything. My greatest responsibility is raising them. As they get older, the decisions get a little bit more precarious and the worries get less but more intense. I have parented differently from my father - I wouldn't wish that parenting experience on anyone I cared about, because it came with its pains, despite its intentions. I've tried to take the best from it, and teach them the things I held on to that were good.Agassi went on to add that his kids were pretty normal, while revealing that Jaz often wanted to do ‘unreasonable’ things, explaining,"Our kids are relatively typical. On an average day when my daughter isn't at school or listening to music in her room, she'll be asking us to go do something that's unreasonable! Our son is home-schooled and is training for his objectives in baseball. When I'm away, I always wear a necklace he made for me when he was five, which is made of beads spelling out 'daddy rocks'.”Andre Agassi rose to fame in the tennis world in 1988 as a teenage phenom. He went on to win eight Grand Slam titles over the course of his career. However, the American famously had a difficult relationship with the sport.
