“I am not young enough to know everything.”

Oscar Wilde

Sometimes being young and ignorant is the best state of mind to start a business, emigrate, quit your job, sail around the world. If you knew all the risks and peril ahead of you, then you probably wouldn’t start.

The upside of age and experience is that you skip the upfront thrash of mistakes and false starts.

The downside is that you know where all the problems are, so you don’t leap until there’s limited downside. Unfortunately those risk free moments are scarce.
