In the poem "The Main Reason I Can't Sleep," Josh can't sleep before the big game because he is filled with excitement and anticipation. He is nervous about the outcome of the game and worried about letting his teammates and coach down. Additionally, he may have thoughts of previous games and mistakes he has made, which keeps him awake worrying about repeating them. The pressure to perform well and the adrenaline rush of the upcoming game prevent Josh from being able to relax and fall asleep.
