Vc se lembra daquela frase... " God Protecs me from what I want" 
É isso mesmo.. nem sempre o que queremos é essencialmente aquilo que precisamos.  Uma pequena mostra disso fica bem ilustrada na mensangem a seguir do site :

You Can't Always Get What You Want 

Rolling Stones

Composição : Keith Richards / Mick Jagger

I saw her today at the reception
A glass of wine in her hand.
I knew she was gonna meet her connection,
At her feet was a footloose man.
And you can't always get what you want,
Honey, you can't always get what you want.
You can't always get what you want
But if you try sometimes, yeah,
You just might find you get what you need!
I went down to the demonstration
To get our fair share of abuse,
Singing, "We gonna vent our frustration."
If we don't we're gonna blow a fifty amp fuse.
So, I went to the Chelsea Drugstore
To get your prescription filled.
I was standing in line with my friend, Mr. Jimmy.
And man, did he look pretty ill.
We decided that we would have a soda,
My favorite flavour was cherry red.
I sing this song to my friend, Jimmy,
And he said one word to me and that was "dead."
And I said to him
And you can't always get what you want, honey.
You can't always get what you want.
You can't always get what you want.
But if you try sometimes, yeah,
You just might find you get what you need!
I saw her today at the reception.
In her glass was a bleeding man.
She was practiced at the art of deception;
I could tell by her blood-stained hands.
And you can't always get what you want, honey.
You can't always get what you want.
You can't always get what you want,
But if you try sometimes, yeah,
You just might find you get what you need!
And you can't always get what you want, honey,
You can't always get what you want,
You cant always get what you want,
But if you try sometimes, yeah,
You just might find you get what you need
