Don't listen to that guy John Gray.
It is only needed his sentence for the purpose of life to understand, that he is just a lazy, old, senile, idiot witgh absolutely absent will for development and growth.
"to live just long enough to do what i want to do ; to see what i want to see ; to enjoy what i've wanted to enjoy;.. " "a type of completion. "
His life is to fuck several (maybe high class) whore bitches, to get drunk several times with the best alcohol he may get, to go to several high class coupons, to eat like a pig several times, and that's all. I won't be surprised if he does not mind to shoot himself in the head right now in this moment. He is absolutely missing any long term ideas for a better life.
If his needs were for example to read all of the good books, then he would notice, that he can't do that, because new books will always appear. And there always will be another good book waiting to come out after the moment of his death in the limited life. Simmilarly he can't watch all of the good movies, can't listen to all of the good songs, can't get the best of any joy, because all types of joy develope, and there always will be maximum at the timepoint of his death. Thus he can't ecven fuck, drink, coupon and eat enough. He is screwed in his birth. There is no best joy in a finite life.
I wonder how such senilized cretenoids are still in a job as a big scale phylosophers, and take the plce of really progressive minds.
