Make Time is the second book of Jake Knapp and John Zeratsky, following the successful Sprint. The book introduces four important steps of making time- Highlight, Laser, Energize, and Reflect. They also shared about 90 tactics that are derived from their personal experience as well as evolutionary psychology.
Overall I believe everyone who needs to make a living should read this book, with a grain of salt. Things might be applicable or not depending on the situation, but the out-of-box thinking of liberating from a day job will for sure bring value regardless of your status.
