Whenever we are tempted to throw good money after bad in terms of human living, let's stop and ask ourselves these three questions: 1. How much does this thing I am worrying about really matter to me? 2. At what point shall I set a "stop-loss" order on this worry---and forget it? ...Decide just how much anxiety a thing may be worth---and refuse to give it any more. 3. Exactly how much shall I pay for this (thing)? Have I already paid more than it is worth?
