A lot of the problems we have in the world right now are because people want things that they don’t need, like a new phone every two years for example, and it creates a constant dissatisfaction with the present.
I wonder if this is why rich people kill themselves? They have so much, and not knowing what to do with it and not having time to use it must create additional layers of dissatisfaction.
The focus on living in the present moment that Marcus Aurelius wrote about reminds me of Buddhism. Aurelius even says that we shouldn’t worry about the past or the future because they do not exist.
