We seldom think of what we have but always of what we lack. Therefore, rather than grateful, we are bitter.
In the blessings as well as in the ills of life, less depends upon what befalls us than upon the way in which it is met.
Whether we are in a pleasant or a painful state depends, finally, upon the kind of matter that pervades and engrosses our consciousness and what we compare it to - better and we envious and sad, worse and we feel grateful and happy.
