In The Back Of My Mind by Beach Boys

I'm blessed with everything
A world to which a man can cling
So happy times when i break out in tears
In the back of my mind i still have my fears

I live my life with her
Love her true she knows i'm sure
I make her happy just living so plain
In the back of my mind i'm 'fraid it's gonna change

I tried to run far way from thoughts
I should try to keep away
But they just keep coming back to me
I tried to rationalize
But some day i might realize
That things are just good the way they'll be
I know it's so hard to find
A girl who really understands your mind
What will i do if i leave her
It will always be way in the back of my mind
