These things are not for the best, nor as I think they ought to be; but still they are better than that which is downright bad.

Not everything has to be good to be worth keeping. A great deal of ordinary life sits in the middle: the job that is fine, the arrangement that works imperfectly, the relationship that is not what you hoped and is nowhere near bad. Holding out for the ideal often means trading something workable for something worse.

Be honest about where you are on that scale before you make a change. Ask whether the thing you are dissatisfied with is actually bad, or merely not ideal. Improve it where you can, and let it be adequate where you cannot.
