Murphy's Law of Auto Repair and the ASSUME Rule

The truth as seen by a true auto repair pessimist


*See also the 10 Commandments of Car Repair. ASSUME: When you ASSUME you make an ASS out of U and ME.

K.I.S.S.: Keep It Simple Stupid.

Murphy's Laws:

  1. Nothing is as easy as it looks.
  2. Everything takes longer than you think.
  3. Anything that can go wrong will go wrong.
  4. If there is a possibility of several things going wrong, the one that will cause the most damage will be the one to go wrong. Corollary: If there is a worse time for something to go wrong, it will happen then.
  5. You never run out of things that can go wrong.
  6. If anything simply cannot go wrong, it will anyway.
  7. If you perceive that there are four possible ways in which a procedure can go wrong, and circumvent these, then a fifth way, unprepared for, will promptly develop.
  8. If everything seems to be going well, you have obviously overlooked something.
  9. It is impossible to make anything foolproof because fools are so ingenious.
  10. Whenever you set out to do something, something else must be done first.
  11. Every solution breeds new problems.
