“Thousands of people with good qualities are displeasing; thousands pleasing with far less abilities, and why? Because the first wish to appear to be what they are not, the second are what they appear. Some of the advantages or disadvantages that we have received from nature please in proportion as we know the air, the style, the manner, the sentiments that coincide with our condition and our appearance, and displease in the proportion they are removed from that point.”

Context: I learned to look more upon the bright side of my condition, and less upon the dark side, and to consider what I enjoyed rather than what I wanted; and this gave me sometimes such secret comforts, that I cannot express them; and which I take notice of here, to put those discontented people in mind of it, who cannot enjoy comfortably what God has given them, because they see and covet something that He has not given them. All our discontents about what we want appeared to me to spring from the want of thankfulness for what we have.
