beach boys - in the back of my mind lyrics

(brian wilson)
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
