Yes you can. But you have to make really popular vids and up to a million views for your videos. You also need more than 1,000 subscribers and on one of your YouTube vids, there has to be a button that says make money off this video and you can start from there. You can't just start making money off a new account, new video.

It is easy. If you make videos that thousands of people will watch and can make a living doing it or like doing it then why work for someone else?
Make your own hours, do what you love and pay your bills. Before you can start making money off of your videos, you need to enable monetization on your YouTube account.
