I arise in the morning torn between a desire to improve (or save) the world and a desire to enjoy (or savor) the world. This makes it hard to plan the day.

This quote means that when we wake up each day, we can be unsure between whether we should focus on making the world a better place (like volunteering or helping people), or focus on enjoying what the world has to offer (like going on vacation). This can be difficult and make it hard to decide how to plan out the day.
