Hill's Commentaries on Murphy's Laws (laws) 1. If we lose much by having things go wrong, take all possible care.
2. If we have nothing to lose by change, relax.
3. If we have everything to gain by change, relax.
4. If it doesn't matter, it does not matter.
O'Toole's Commentary
Murphy was an optimist.
NBC's Addendum to Murphy's Law
