One of the best ways to develop your ability to read copy is to pick any piece thats at least 5 or 6 pages long and cold read it. Take the time you need to read it perfectly. Remember to scan ahead with your eyes as you take a breath for the next sentence. Your eyes should always be 2 or 3 words ahead of where your mouth is speaking so you can deliver ideas and not just the words.
There is something amazing that happens to everyones talent when they spend a lot of time reading out loud, they get a lot better.
Happy 4th everyone!
