He is very famous as he wrote a set of rules for living a more organised and therefore peaceful life. He also happened to be a Roman emperor so this was quite crucial for him to get everything done on time. He has much in common with Seneca and Stoicism in this respect. So the 2 are often read together to see how they compare and contrast.
A major point that Marcus mentions is to live your life as though you are going to die soon. While this may sound rather morbid and counterproductive; it is in fact sound advice. You are now motivated to do the most important things in life and that is to spend time with your family, friends and enjoying yourself by indulging in hobbies. You are no longer exclusively focused on hard work.
Marcus is part of the group of stoic philosophers that include Seneca the younger, Cato and Epictetus. There all from around the same time but with widely different viewpoints due to their unique lives. This helps enormously as you will always be able to find something useful since they will most likely have experienced it.
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.
