I want to want more.

Hi, I don't know anything anymore so I just wanted some advice.

My life just feels.. complete, Like I've lived it fully. I can look at my art and go "Yeah, that's ok." I can look at my belongings and not want anything else, I don't want any gifts for my birthday or anything. I have the drive to get out of bed and go to school, even though I'm tired sometimes. I have straight A's. But as I cross another thing off my bucket list there's a point where I don't have anything to replace it with, and so now I'm only down to 2 things and that's it. I'll probably just end my life when I'm done, not out of depression, or anything else. It's just the knowledge I've lived a full life, I have no wants. But. I want to want. I want to stay alive and have a drive. I just can't think of anything.

So, my question to y'all is;

What gives people a drive? And how can I restore mine?
