I started making videos here and there in middle school, and my first few years of high school. I actually gave it up, simply because I didn't have any clue as to what I was doing.
I ended up switching schools after my sophomore year of high school, and spent that summer in an area where I had no friends Dx. So, I decided to pick up youtube again and make a honest effort into it. It really helped speed up that summer, and I kept with it ever since. It's now my biggest hobby, I actually gave up football and skateboarding. I even quit the skate team I rode for in my home town xD Might not have been a great idea if you look at my channel size, but I'm glad I did. YouTube is my biggest passion, and can't believe that I didn't start sooner!
So how and why did you get into youtube?
