I would only add one more thing to what has already been said. Be careful to not speed up your construction. It is real easy to get trapped into going faster than you should. Always, always, make sure the step you are about to take is the right one. It is real tempting to try to speed up construction even on easy parts. When you do, you are asking for trouble. As it has been said, make sure you are following what the instructions indicate. It is real easy to read them fast, think you know what is required, and make a mistake. I know I have done this myself.
