Edith to the last post:

What I realized I forgot to add to that last one was why it was such a big deal.

If you don't figure out early how you're going to deal with problems, it is much harder to deal with problems once they've arrived. Prevention is better than a cure, it's easier to correct a little wobble in the driving now than fix a broken car once you've crashed, (or try to correct your course when you're about to crash), etc etc.
