By realizing that the other 1/3 of our lives are spent on what is meaningful to us. And the 1/3 that is work funds more resources to put towards what is meaningful. I can go buy expensive tools and supplies for my sculpture hobby. I can afford gas and hotels to explore the country. I can go out to eat with my friends and family. And the last 1/3 is sleep... which isn't really a negotiable part of the human existence.

Also, don't discount weekends. You don't really work 1/3 of your life because you get 2/7ths off every week.
