I thought it was time for a little Thomas Watson on contentment:
There are three things which contentment doth banish out of its diocese, and which can by no means consist with it.
1. It excludes vexatious repining; this is properly the daughter of discontent: ‘I mourn in my complaint.’ He doth not say I murmur in my complaint. Murmuring is no better than mutiny in the heart; it is a rising up against God. When the sea is rough and unquiet, it casts forth nothing but foam: when the heart is discontented, it cast forth the foam of anger, impatience, and sometimes little better than blasphemy. Murmuring is nothing else but the scum which boils off from a discontented heart.
2. It excludes an uneven discomposure: when a man saith, I am in such straits, that I know not how to evolve or get out, I shall be undone; when his head and heart are so taken up, that he is not fit to pray or meditate, he is not himself: just as when an army is routed, one man runs this way, and another that, the army is put into disorder; so a man’s thoughts run up and down distracted, discontent doth dislocate and unjoint the soul, it pulls off the wheels.
3. It excludes a childish despondency; and this is usually consequent upon the other. A man being in a hurry of mind, not knowing which way to extricate, or wind himself out of the present trouble, begins to faint and sink under it. For care is to the mind as a burden to the back; it loads the spirits, and, with overloading, sinks them. A despondent spirit is a discontented spirit.
