Just do it! Go for it and have fun with it. That's what I did in 2012. I felt like doing the same thing, especially because I was moving to Seoul. I wanted to share my experiences with everyone.
Now my channel has grown to more than 15k subscribers (not that big compared to others), and it opened up many opportunities for me.
You don't even have to vlog, if you're camera shy. Make the type of videos you want and be yourself. ^^
