Read a lot. Write a lot. Just go for it.
It puzzles me constantly when I hear about writers (aspiring or not), that never read books. How can they even begin to think that they can write if they don't read and feel what others have written? Also ... don't go around and think about writing. Just do it. What could go wrong? The worst which could happen is that you have to delete, what you just wrote, and come on ... I think we have wasted more time on playing games on your telephone. Besides ... it is not a waste of time. You just learned something.
