Buvaisar Hamidovich Saitiev, also spelled Buvaysar Hamidovich Saytiev, (Russian: Бувайсар Хамидович Сайтиев, Chechen: Сайт КIант Бувайса) (born March 11, 1975 in Khasavyurt, Dagestan ASSR) is a Russian wrestler of Chechen heritage, who has won nine world-level gold medals in freestyle wrestling. He Is widely considered the greatest freestyle wrestler of all time. 
Buvaisar's life philosophy has been heavily influenced by Nobel Prize-winning poet Boris Pasternak. Saitiev repeats the following poem before every match, and according to Buvaisar, the poem has defined his life both inside and outside of wrestling:
It is not seemly to be famous
Celebrity does not exalt;
There is no need to hoard your writings
And to preserve them in a vault.
To give your all - this is creation,
And not - to deafen and eclipse.
How shameful, when you have no meaning,
To be on everybody's lips!
Try not to live as a pretender,
But so to manage your affairs
That you are loved by wide expanses,
And hear the call of future years.
Leave blanks in life, not in your papers,
And do not ever hesitate
To pencil out whole chunks, whole chapters
Of your existence, of your fate.
Into obscurity retiring
Try your development to hide,
As autumn mist on early mornings
Conceals the dreaming countryside.
Another, step by step, will follow
The living imprint of your feet;
But you yourself must not distinguish
Your victory from your defeat.
And never for a single moment
Betray your credo or pretend,
But be alive-this only matters-
Alive and burning to the end.
— Boris Pasternak, My Sister Life
Быть знаменитым некрасиво.
Не это подымает ввысь.
Не надо заводить архива,
Над рукописями трястись.
Цель творчества самоотдача,
А не шумиха, не успех.
Позорно ничего не знача,
Быть притчей на устах у всех.
