Adam. There are a thousand ways to go about being a writer but you essentially need only two things; A pen and a piece of paper.
Write as often as you can. Write about anything and everything. Just don't stop. I would also advise you to read as much as humanly possible because I always believed that great writers are great readers. You will get inspired from the books you love and it will show in your work. Also, don't shy away from imitation. Most idea's come from other ideas anyway. Read. Write. Repeat.
