It's hard to be a writer. Though you have words, you need to have feelings and imagination as well to be able to create a story. 

Since that is the case, perhaps, some writers grow from chaos or harmony and in between. That's why they can write every piece of their heart out in the most cunning ways.

If you want to become a great writer, you just need to build your confidence because without it, you can never touch a single pen. But I believe in you. So write if you have time.
