If you want to get better at writing, be deliberate: practice with the goal of learning and becoming better. (1) read good works and study their authors' choices and techniques, (2) write often to strengthen your writing muscles and develop your style, (3) practice rewriting and editing (your writing and others), and (4) get feedback on your writing. Books on writing can help, but there is no subsitute for doing the work. Being deliberate about learning from the work, however, will speed your improvement. With regular work, you'll be noticably better after a month or two, especially if you're getting feedback. After a year, you'll be a different person. Your writing will be faster, easier, and better. But don't stop then. You're just getting started :-)
