Alone, Is It Survival or Living?

Somehow, I ended up in a world where I am the only person, a world I think about before going to sleep. Every moment here, I ponder the meaning of being alive. Should I work hard to improve myself, so that if I somehow return one day, I can look back with pride? Or should I just **drift through life in this empty world? If I'm alone, am I surviving, or truly living?
