Beibut Shumenov has 19 professional fights and 17 wins, 11 by KO. He is the first to win light heavyweight champion title after 10 professional fights. This record still has not been broken by anyone.
To succeed, you have to believe in yourself, work every day and never give up. There will be failures, but do not give up on your dreams. In my experience, I've come to understand that nothing is impossible.
