This is what the ancient world practised to ensure that they made the best use of their time. They didn’t have all of the electronic distractions that we do but they did have a lot more children so their issues were more immediate and pertinent. Such things as hunger, thirst and death from diseases which we have mainly stopped. So they had good reason to optimise the short lives that they had. It also means that if we follow their lead we will also benefit from there advice as it has passed the test of time.
Watch Seneca here for some golden rules to follow for better time management.
Seneca was a famous Roman philosopher who has been used through the ages by many people to gain an insight into how they can be the most productive version of themselves. Recently Americans interested in promoting alternative lifestyles that are now possible like the location independent or digital mimialistic ones use stoicism as there cornerstones. Look here at Cal Newport for more information on the subject. There are many others who talk about this like Gary Vaynerchuk, Tony Robbins, Tim Ferris and Scott H Young. I don’t get money from any of them.
