The 25-year-old defender played the 200th game of his career in the thrashing of Hull last weekend and he is loving life with the Cherries, while saying he aims to be at the club for a long time.
Cook has an eye on reaching bigger targets in the future even though he understands he may not be one of the fans' favourite players.
He told the Echo: "It's gone in the blink of an eye. I love it here and I love playing for the club. I'm not one of the fans' favourites and maybe every year there are calls for me not to be in the team.
"But I'm still here. The gaffer's got faith in me and it's up to me to improve and keep myself in this team.
"I'm still only 25 so, hopefully, my best days are ahead of me and I want to go on to make 400 or 500 appearances, so that is my next target.
"I've made a lot of appearances in a short amount of time. I can't remember how many games I've missed but it's not too many. It's pleasing and I'm hoping to build on that and, hopefully, stay here for a very long time."
