Giving advice on writing depends to a great extent on what type of writing interests you. People make the mistake of thinking writing is like videotaping your daydreams. Daydreams are wanderings, writing is a carefully planned trip with the car tuned up, well stocked, your hotels planned out, your gas allowance set and a Plan B. You have to have native talent or you're halted then and there. Assuming you do, you then have to develop it through education and lots and lots of practice. Assuming you develop it, it helps to be in a position where you are needed to write a certain thing. Your ability to do that successfully gives you a resume you can take around with you when you want to write something on your own nickel.
