But all the time, Justin continued to build his fan base on his YouTube account, where some of his original home videos can still be found, and where he continues to post music. "I wasn't sending mixtapes or anything like that to record labels," he told us when we met him on his promotional tour for his latest film Justin Bieber: Never Say Never. "I was just doing regular stuff at home and I just posted videos online without purpose. I would never be here if it wasn't for the Internet and YouTube."

Article: Home to me means a sense of familiarity and nostalgia . It's fun to come home. It looks the same. It smells the same. You'll realize what's changed is you. Home is where we ran remember pain, live, and some other experiences; We parted here; My parents met here; I won three championships here. If I close my eyes, I can still have a clear picture in mind of my first home. I walk in the door and see a brown sofa surrounding a low glass-top wooden table. To the right of the living room is my first bedroom. It's empty, but it's where my earliest memories are. There is the dining room table where I celebrated birthdays, and where I cried on Halloween-when I didn't want to wear the skirt my mother made for me. I always liked standing on that table because it made me feel tall and strong. If I sit at this table, I can see my favorite room in the house, my parents' room. It is simple: a brown wooden dresser lines the right side of the wall next to a television and a couple of photos of my grandparents on each side. Their bed is my safe zone. I can jump on it anytime - waking up my parents if I am scared or if I have an important announcement that cannot wait until the morning. I'm lucky because I know my first home still exists. It exists in my mind and heart, on a physical property on West 64th street on the western edge of Los Angeles. It is proof I lived, I grew and I learned. Sometimes when I feel lost, I lie down and shut my eyes, and I go home. I know it's where I'll find my family, my dogs, and my belongings. I purposely leave the window open at night because I know I'll be blamed by Mom. But I don't mind, because I want to hear her say my name, which reminds me I'm home.
