科比退役的原文英文版如下：

Dear Basketball,

From the moment I started rolling my dad’s tube socks and shooting imaginary Game-winning shots in the Great Western Forum, I knew one thing was real: I fell in love with you. A love so deep I gave you my all—from my mind & body to my spirit & soul. As a six-year-old boy deeply in love with you, I never saw the end of the tunnel. I only saw myself running out of one. And so I ran. I ran up and down every court after every loose ball for you. You asked for my hustle, I gave you my heart because it came with so much more. I played through the sweat and hurt not because challenge called me, but because you needed it.

I’ve lived a life that’s been filled with countless ups and downs, and through it all, basketball has been my constant companion. It’s more than just a game to me； it’s a part of who I am. I’ve given everything I have to this sport, and in return, it has given me so much. The memories and the victories, the failures and the lessons, they are all etched deeply into my soul.

As I stand on the precipice of retirement, I want to take this moment to thank you, basketball. Thank you for the joy, the thrill, and the sense of accomplishment that you’ve brought me. Thank you for the friendships and the bonds that I’ve formed through the years. You have shaped me into the player and the person that I am today, and for that, I will always be grateful.

I know that this is not the end of my journey, but rather a new beginning. I will always cherish the time I spent playing for the Los Angeles Lakers and for the fans who have supported me throughout my career. I will continue to pursue my passion for basketball, but in a different capacity. I will be a coach, a mentor, and a source of inspiration for the next generation of players.

Once again, thank you, basketball. You have been my greatest love and my greatest teacher. I will miss you dearly, but I am excited to embark on this new chapter of my life.

Sincerely,

Kobe Bryant
