Ahmed, I learned that books don't write themselves. :-) To work toward that dream of yours, start writing down ideas you have for books and sketching outlines as you think about them. Something might grow into a good story that excites you and motivates you to give it a try.

I have notes with ideas for numerous books I'll probably never write. It's a valuable experience to just start thinking about them, writing thoughts down so you don't lose them, and see where they take you.
