I can still remeber what the teacher  has written on the F.6 notes:
F.6 work hard -> F.7 no pain
F.6 honey moon -> F.7 die hard

I think I've done my best to work hard when I was F.6...But...
It seems that it violates the principle of  "no pain, no gain"...
 

May be Lenka is right...
Trouble is a friend but Trouble is a foe
And no matter what I feed him he always seems to grow
He sees what I see and He knows what I know
So don't forget as you ease on down the road
He is there in the dark,
He is there in my heart
He waits in the winds,
He is gonna play a part
Trouble is a friend, yeah
Trouble is a friend of mine
