There is always a warning. There is always a sign.
You should be prepared, and yet you are not. Partly because it is easier to think at life as a straight, uninterrupted line. Partly because most warnings are encrypted, unclear, have mixed words, and it is only easy to spot them afterwards.
And so, when something happens to you, searching ex post for warnings and signs is pretty much useless. Think instead about where you can go from there, and whom with. That is how you will unlock the potential of the situation.
