>The purpose of life is to enjoy your time alive in this world.

You don't get to decide what the purpose of life is. And wanting to leave your mark on the world is just as validation a purpose of life.

>The way to be remembered is to live a life worth remembering after all.

Yeah that doesn't actually mean anything. There are plenty of people forgotten by time and their ancestors who lived perfectly fulfilling lives with their friends and family. They never got remembered in history books. Not that I'm saying their choices were worse but if you want to be remembered in history books, you don't just sit around making friends and family.
