Who Is The Happy Man? He Who Is Content With His Lot

After 25 years of lecturing on happiness, writing a book on the subject (“Happiness Is a Serious Problem”) and devoting an hour of my radio show every week for the last 13 years to happiness, here are some conclusions about who is happy.
People who control themselves.
Happiness is dependent on self-discipline. We are the biggest obstacles to our own happiness. It is much easier to do battle with society and with others than to fight our own nature.
People who are given little and earn what they have.
That is why lottery winners are rarely happier than those who have far less money — they didn’t earn their newfound wealth. And they are often less happy after their win than they were before it.
So, too, those who get used to receiving unearned material benefits (such as government entitlements) are likely to be unhappier than they were before receiving those benefits — and much less happy than those who have earned whatever they have. That is why the entrepreneur who has worked day and night for years is usually happier than the person who inherited vast wealth.
