ah, but what about the journey, not the destination

If "the journey" is your peace and happiness, etaoin, you do not have "a strong desire" for it. You are too busy living it, and enjoying it, in the moment.

If, on the other hand, "the destination" is the reason for your journey, you may have to suspend your peace and happiness until you get there.

"Strong desires" can be sublimated, etaoin, but usually they have to be sated or extinguished to achieve a condition of meaningful peace and happiness.

The American Heritage Dictionary defines "concupiscence" thus:

"A strong desire, especially sexual desire; lust."

A person can have a "strong desire" for peace or happiness, but they won't experience either one until they lose their desire for it.

I think it is probably true that most of us have to desire peace or happiness to find them, but, once found, desire, like dew, evaporates in the morning sun.

Some people find peace and happiness without looking for them. Or even desiring them.

Whoever wrote "Zipidee Doo Dah" understood that.

"Zipidee Doo Dah, Zipidee Ay
My of my, what a wonderful day
Plenty of sunshine, plenty all day
Zipidee Doo Dah, Zipidee Ay."

Kids who are loved and cared for don't have to look for peace and happiness.

They just have to rediscover them once they grow up.
