Buffon reached the landmark in victory over Livorno.
"You need to be a little bit daft, along with having quality, the right mentality and the desire to live a steady life," the 35-year-old Buffon said. "I was an adolescent when I started playing and I didn't have much of a beard.
"Now my beard's thicker and features a few more white hairs, but I've kept a bit of that positive craziness that has helped me over the years.
"I don't know if I'm the strongest today but I know that I have to prove myself all the time.
"At my age, you cannot afford the luxury of making mistakes.
"I feel stronger than when I was a youngster and when I am focused, it's difficult for me to make a mistake in a game."
