Facadesaside: Life changing moments?

This blog went over life changing moments as perhaps philosophically dubious or empirically dubious.

The case seems radically similar to the problem of contingent truths.

One only knows about change in her life because of difference between similarities.

We believe in contingent truths because everything looks the same.

So when you go into a forest and all of the trees look the same, you believe that you have a choice to cut down a tree between any tree in the forest.

If you went into a "forest" of one tree, you would of course be limited to that one tree.

Okay for option three, put all of your trees back. But this time, recognize the fact that they all look different. One is knotty and therefore impossible to use for chopping wood. One is just a baby tree and should not be cut down. Some wood is better for fire-building than others. It starts to look more and more like the second option more than the first. You are limited after all.

This is merely a thought experiment to show that contingency is a difficult concept.

Applied to our initial topic, this is even more difficult. At what point is something life changing? If your life is necessitated as opposed to contingent, every little thing counts.
