As a writer I've learned a lot when it comes to writing my novel, The Generation. I've made mistakes like editing as I am writing my first draft. It is why I am still writing that novel. But without making those mistakes we would never learn.
In addition, I remember a friend once told me that instead of wasting your life watching soap operas and playing video games, why not learn something. Something like, "Learn how to get people to watch your videos - http://t.co/AFGkoYiFeZ"
Makes sense, don't you think?
