Learning to want what we already have

From time to time I pick up one of my books on the ancient philosophy of Stoicism.  I find it very helpful when I feel unsettled or unmoored - when there is a lot of change happening.  There are many valuable teachings in Stociscm, this one teaches that we can free ourselves by wanting less.  "It is impossible that happiness and yearning for what is not present should ever be united." - Epictetus
