Why you feel need to do more? It is because society told you story of "hustle hustle till you die"? When was the last time you took walk in nature? When was the last time you lay down on grass on night and watch stars? When was the last time you played sports? When was the last time you volunteer for something? When was the last time you called someone after long time and check if they okay? When was the last time you watched bird fly in V shape?

I mean I understand you but sometimes not every seconds needs to be inside "utility function". Again you need strip out every assumption, belief about life that society has inscribed on your mind. Trust me, you will feel the same once you become Google CEO too. There is no "this is enough" point in future.
