Stoicism (Stoicism) is an ancient Greek philosophical school founded by Zeno of Citium in the 3rd century BC. Stoicism teaches that happiness can be achieved by living a rational and wise life, and by detaching oneself from negative emotions.
Stoicism emphasizes that only those things that are within our control are important. Things that are beyond our control, such as natural events or the actions of other people, are things that we cannot change. Therefore, we don't need to worry or be angry about these things.
Stoicism teaches that we should focus on the things we can control, such as our own thoughts and actions. By controlling our thoughts and actions, we can live happier and more peaceful lives.
