“The time that you’re alive is the only thing you truly possess, and you can give it away. You can give it away by working for other people—they own your time and you can be miserable. You can give it away by reaching for external pleasures and distractions—spending the time that you have as a slave to different passions and different obsessions. Or you can make the time that you’re alive your own.”

Robert Greene, The Daily Laws (Page 426)
