Your life experiences, thoughts, ideas, videos, audio, pictures.. EVERYTHING is content.
I'll say it one more time because it's so vital that you know this, every single thing is content. It might seem weird, but it's true. Think for example a picture of dog poop. Although you might not view it as content, that's one of the reasons websites like funnyjunk are so successful.
There are videos of people singing songs that don't make any sense, yet those videos have millions of views.
People share their thoughts on videos all the time (for example when that guy shot his daughters laptop) although he may not have known it at the time, he was creating one of the most talked about youtube videos just by sharing his opinions.
Content is everywhere.
Stop worrying so much and just use what you have.
