What is the meaning of you have had your shelves in the song We are the champions?

Answer 1

There is no line "you have had your shelves" in the song "We Are The Champions" by Queen. You are probably referring to the line "I've had my share of sand kicked in my face, but I've come through". The line means that even though the singer has faced an amount of tribulations comparable to most people, he has overcome them, on the way to becoming a champion.
I've paid my dues -
Time after time -
I've done my sentence
But committed no crime -
And bad mistakes
I've made a few
I've had my share of sand kicked in my face -
But I've come through

We are the champions - my friends
And we'll keep on fighting - till the end -
We are the champions -
We are the champions
No time for losers
'Cause we are the champions - of the world -

I've taken my bows
And my curtain calls -
You brought me fame and fortuen and everything that goes with it
-
I thank you all -

But it's been no bed of roses
No pleasure cruise -
I consider it a challenge before the whole human race -
And I ain't gonna lose -

We are the champions - my friends
And we'll keep on fighting - till the end -
We are the champions -
We are the champions
No time for losers
'Cause we are the champions - of the world -
