"In South Africa, they dig for diamonds. Tons of earth are moved to find a little pebble not as large as a little fingernail. The miners are looking for the diamonds, not the dirt. They are willing to lift all the dirt in order to find the jewels. In daily life, people forget this principle and become pessimists because there is more dirt than diamonds. When trouble comes, don’t be frightened by the negatives. Look for the positives and dig them out. They are so valuable it doesn't matter if you have to handle tons of dirt."
