There is no health in those who are displeased by an element in Your creation, just as there was none in me when I was displeased by many things You had made. Because my soul didn't dare to say that my God displeased me, it refused to attribute to You whatever was displeasing.
A sense of contentment is crucial to being happy. Physical health, material wealth and friends contribute to this, but contentment governs our relations with them all.
If we will take the good we find, asking no questions, we shall have heaping measures. The great gifts are not got by analysis. Everything good is on the highway. The middle region of our being is the temperate zone.
May you live unenvied, and pass many pleasant years unknown to fame; and also have congenial friends.
[Lat., Vive sine invidia, mollesque inglorius annos
Exige; amicitias et tibi junge pares.]
