“...a man's worst difficulties begin when he is able to do as he likes.”

That's possible for folks of the ex Soviet Union, Mike. They did not know how to handle thinking for themselves.

Time, whose tooth gnaws away at everything else, is powerless against truth. THH

A man's worst difficulties begin when he thinks what he likes is good for him but it's really not.

When a man does what he likes instead of what is right, he deserves what he gets. Everyone else's worst difficulties begin when he compels THEM to do what he likes.

Cute but not universally true. Of course when raising children I realize that giving a child everything he/she wants is a disservice to the child. Without an effort, there is no value to whatever one gets for free or expects for free.
