A 4-year-old boy from Chicago helped inspire the world of social media by proving nothing is impossible when he successfully read 100 books in a day, a feat that was streamed live by the child’s father on Facebook Live.

When Caleb Green decided to take on the challenge of reading 100 books in a day, the initial struggle for his parents was to find the magic number of books. His parents scoured through their stock on the bookshelves and found they were running slightly short of Caleb’s requested target. Hearing of his astonishing goal, some of Caleb’s friends decided to help out by dropping off a few books at his doorstep.

After the initial hurdle of finding 100 books was solved, there was still the question of Caleb actually taking on what at his age was nothing less than a herculean task. In order to spare him possible disappointment if he did not manage to accomplish his self-set goal, Caleb’s father Sylus Green tried to pacify the situation.

"I was like, 100, son? That's a lot of books,” Sylus told ABC affiliate Eyewitness News. “So at first, I had the gut reaction to talk him down a little bit but he was like, 'No, I want to read 100.'"

Sylus and his wife decided to live stream Caleb’s marathon reading on the social media – an effort that soon went viral, with views coming in from as far as Florida. Caleb also found a way to keep himself motivated throughout the challenge. He would do a little dance every time he completed reading 10 books.

Once he successfully completed reading 100 books, Sylus admitted there was a lesson to be learnt from his 4-year-old son’s resolve.

"I learned to just dream bigger and I am going to set unrealistic goals for myself this coming year and I'm going to be inspired by Caleb to not quit on him and just push through it," he said.

Despite being a bookworm and avid reader from such a young age, Caleb had quite different aspirations of what he wanted to become when he grew up.

"I want to be a basketball player. When I am 22 I want to be an astronaut and when I'm 23 I want to be a Ninja turtle," Caleb said.
