......Michael Bywater's article in the London Telegraph. Based on his book Big Babies.
While I doubt I share many of his political sympathies, I share most of his take on the lack of actual adults in the world. Warning: some coarse language in the article. Didn't offend me, but I wanted to give you a heads up.
Here's a snippet, at the end of the article, where he gives rules for How to be an Adult:
Ignore celebrities, except when they are doing what they are celebrated for doing: acting, playing football et cetera. Skill does not confer moral, political or intellectual discrimination. (Except in the case of writers. Writers know everything and can lecture you with impunity.) If a celebrity is not celebrated for doing anything but being a celebrity, smile politely but pay no notice
Suspect administration Its purpose is to free the organisation to do what it's meant to do: but the triumph of the administrators - the lawyers, the accountants, the professional managers - means that too many organisations now believe that what they are meant to do is administer themselves. This is a profoundly infantile attitude
Do not love yourself unconditionally. Such love is for babies and comes from their mothers.
Ignore fashion, particularly in clothes. You don't want to look like a teenager for ever
Denounce relativism at every turn. Shouting 'not fair' is childish. Demanding respect without earning it is childish. Don't fear seriousness. Babies aren't allowed to be serious
Hide Grown-ups are not required to be perpetually accountable, while the instincts of government and big business, both of which are, almost by their nature, great infantilisers, are to keep an eye on everyone all the time
Eat it up There is nothing more babyish than having dietary requirements
Never vote for, do business with or be pleasant to anyone who uses the words 'ordinary people'
