I think my brother was watching him on Youtube and he was watching Pewdiepie play Happy Wheels (last year) and then beginning of this year I found him again and then subscribed to him because he was entertaining and inspiring.
Pewdiepie just came in as a daily thing to do, like after school watch Pewdiepie and iisuperwomanii. Pewdiepie just makes my days a lot easier and happy. He's a very inspiring YouTuber that love what he does and we should all do something that we enjoy doing.
