Wire Fishing

i need to fish cable through my walls?
I have to run my cable wire in my attic through the walls of my bedroom. What is the easiest way to find where to drill my hole and start fishing my cable also ive never did this before any advice?
You could go to a rental shop and ask them for the film "fish." It is a tool for electricians. What is a rigid thin flimsy flat ribbon (as a wire plane) that comes in a "reel" .. It is best implemented through a tube (a hollow tube like apparatus). If you can get some pvc pipe or to get from point A to point B. .. it was easy. Then go in your fish tape from point B to point A.. then tie a string on the end Ribbon fish "... pull the string back to the point B. Cut the string at point A, leaving a lot of extras, then join him in his wire and pull the same. You can also make an over-sized hole in the wall on both points, so you can see the inside ... hope that your cable is "hard" as to "push through the wall" .. mowing and a coat hanger. Make a "hook" at the end of his suspension. You will need a flashlight to help see inside the wall. Have a helper push the wire to point B. Then just look for the wire, "the hook with the hook for suspension" and then pull it. If you must make many turns, you may have to make a hole in each corner, then continue until you reach your thread where you need it. Fill the holes with a small "Joint compound" .. let dry, then sand is soft ... you'll never know the hole was there. Touch up with paint.
