Murphy's Law states that "if there's more than one possible outcome of a job or task, and one of those outcomes will result in disaster or an undesirable consequence, then somebody will do it that way."  to put it simple, "If anything can go wrong, it will, and usually at the most inopportune moment". in english it sounds a bit extreme, but in chinese, it sounds just right :越不想让它发生的事情越会发生.

well, it is so true sometimes, most of the time. but actually it is because we always pay too much attention to those things that we scare that they will happen.

after those things really happened, we feel devastated, demoralized or maybe heart broken. but after going through them, we move on.

and we grow up.
