Do you have any of your work I can see?

One of the reasons why a lot of people stop writing is that it's difficult, very difficult and often very boring. I forget his name, but a man once said "I love writing before I start and when I finish, the rest of the time it's Hell." So when you stop it can be difficult to get your momentum back.

Another reason lots of people struggle is that they try to write before they've got their ideas sorted out. Most of my writing time is taken up by thinking and researching - knowledge is the seed of ideas. Perhaps instead of trying to write, you need to find something that you want to write about?

I hope that helps mate.
