There is a wonderful opportunity knocking at your door, so why don't you answer it? Being intimidated by a new challenge is understandable, but not when it's something right up your alley, like this! You need to get a boost of confidence, and the best place to find it is with your closest friend. Call them up and tell them what's going on. Share your concerns with them and see what they say. They will not only help you see that you can do this, they will help you see that you can succeed.
