Stoicism teaches you how to channel everyday life events in a more constructive and beneficial manner. Stoicism believes that we all have a penchant for negative emotions. It's unavoidable since emotions are something we're born with. You can't escape your feelings, but you also don't want them to take over your life either. As a result, Stoicism provides the answer to how to properly manage our emotions so that we can always maintain a happy and hopeful mentality regardless of the obstacles we face.
“Do not indulge in dreams of having what you have not, but reckon up the chief of the blessings you do possess, and then thankfully remember how you would crave for them if they were not yours.” - Marcus Aurelius, Meditations
