It is a divine VIRTUE to be satisfied with very few things.
“Economy is the foundation of human prosperity. The spendthrift is always in trouble. Prodigality on the part of any person is an unpardonable sin.
The fewer the habits, the better for the man. 
Contentment is the antidote for all the social diseases. We must live an independent life. We must never live on others like a parasitic plant. Every person must have a profession, whether it be literary or manual, and must live a clean, manly, honest life, an example of purity to be imitated by others.
Contentment is the master-key to all success. If the members of my family starve I will not ask money from the people. It is more kingly to be satisfied with a crust of stale bread than to enjoy a good dinner composed of many delicious dishes the money for which comes out of the pockets of others…
Love, yea, love must be demonstrated through deeds.
Love has never been a passive verb, a figure of speech; it has always been an active verb, an ideal reality. The sign of true faith is the service of the believers of God and service must always manifest itself in loving deeds and actions…
The mind of a contented person is always peaceful and his heart is at rest. He is like a monarch ruling over the whole world. How happily such a man helps himself to his frugal meals. How joyfully he takes his walks and how peacefully he sleeps!”
‘Abdu’l-Baha from the Diary of MÌrza Ahmad Sohrab, 24 August 1914, Star of the West – 5, p. 232
