"The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong it usually turns out to be impossible to get at and repair"

This quote by Douglas Adams is a funny way of mentioning the irony of life. It is stating that when something that is expected to be sure-fire stops working, it is frequently difficult to repair. This is because the important things that was supposed to be perfect was not developed to be repaired. It is a suggestion that no matter how much we prepare and prepare, things can still go wrong. It is a suggestion to be simple and accept that life is unforeseeable. It is likewise a tip to be prepared for the unexpected and to have a strategy in location for when things do go wrong. Eventually, this quote is a reminder that life is full of surprises and that we should be gotten ready for anything.
