Provide a great New York experience for my nephew

My name is Olasegun Durojaiye, I am a 22 year old design student and martial artist. I am taking care of my nephew for the summer and want him to have the best New York experience possible. I was featured in Humans of New York. Below is a snippet of my interaction with Brandon (photographer of Humans of New York). 

"His mother wanted a break. You know, it's hectic. She's a single mother. She just bought a house. It's a lot taking care of a kid on your own. She thought maybe it would be a good experience for him to come live with Uncle Olasegun for the summer. As soon as she suggested it, I was like: 'I want to do this. And here's the reason: she did the exact same thing for me. We lost our mom when we were kids. I was really young at the time- like three. Whitney was twelve or thirteen. She and my other sister ended up taking care of me: cooked for me, took me to school, made sure I had a shower, brushed my teeth. Back then I thought she was annoying, because of my ignorance. But now it's crazy for me to think about. It must have been such a burden. She'd be hanging out with her friends, and I was always there. So I'm just trying to pay it forward. I picked him up from the airport last night. I have no idea how the summer is going to go. I like to cook, so I'll cook for him. Maybe we'll paint a little in the evenings. I'm going to teach him some kickboxing on the terrace; hopefully that'll tire him out so that I can get some work done. I'd love to be a father one day when I find the right woman. So it's going to be a good test for me. I'm just hoping he has fun. And when he goes back home, he tells his mother all about the amazing summer he had with his uncle."
