Speaking with moderator Jim Gray at the Milken Institute Global Conference in Santa Monica, Calif., the 40-year-old QB reaffirmed his stated desire to play for several more years.

"I have personal goals. I want to keep playing," Brady said. "I've said for a long time I want to play to my mid-40s. I was told three years, when I was 36, 37, 'You can't keep playing; no one wins Super Bowls (at that age).' It's a great challenge for me. I think I've been challenged my whole life. I feel like I can do it."

Brady guided the Patriots to the Super Bowl for the eighth time this year, an NFL record for any player, and he is a five-time champion. He won his third NFL Most Valuable Player award for the 2017 season after throwing for 4,577 yards and 32 touchdowns.

Looking ahead to his return to action this year, Brady said, "Part of this off-season for me is certainly about still preparing for what's ahead in my next journey, my next mountain to climb with this group of team-mates, but it's also (acknowledging) that a lot of people are getting the short end of the stick in my life -- certainly my wife and my kids," Brady said.

"Football is year-round for me. It's a lot of thought, a lot of energy and emotion put into it, but I need to invest in them, too. My kids are 10, 8 and 5. They're not getting younger, so I need to take time so I can be available to them, too. ... I've really spent the last two or three months doing those things, and I think I'm really trying to fill my tank up so that when I do go back, I can go back and I think I'll actually be, in my mind, a better player, a better team-mate, because I'll be really rejuvenated."

Asked whether he feels appreciated for his accomplishments by Patriots owner Robert Kraft and coach Bill Belichick, Brady replied, "I plead the Fifth. That is a tough question. I think everyone, in general, wants to be appreciated more at work and in their professional life. You have different influences in your life, and I think the people that I work with are trying to get the best out of me. So they're trying to treat me in a way that's going to get the best out of me, and I got to get the best out of myself."

Brady added of Belichick, "He's very respectful to me. We've had a great relationship, a very respectful relationship for a long time, and I feel like he's the best coach in the history of the NFL.

"He has a management style (with) players, and he would say, 'Look, I'm not the easiest coach to play for.' I agree. He's not the easiest coach to play for. But he's the best for me. I think what he's proven is that whatever talent he has, he maximizes his talent."
