夢島で他人に やらされてた練習を努力とは言わねえだろう。

好きな野球(こと)して将来飯食おうなんて図々しい特権、
与えられた宿題(こと)こなした程度で手に入るわけねえじゃん。

"You can't call practice someone forced you to do on the training island 'effort.'
Thinking you can make a living doing the baseball you love—that's a bold privilege.
You really think you’ll earn that just by doing the homework you were given?"
