Take a loooooooooong vacation! LOL
We had a great builder, but we still ran into problems. You will definitely want to swing by the building site OFTEN!

One day I dropped by and they were installing the wrong type of door off the great room... another time the electricians were putting switches in the wrong place. It's good to keep right on top of things to avoid mistakes.
Be prepared for something to go wrong. The timing is so crucial and the weather can play an important factor too. I guess you just need to be flexible but don't let the builder walk all over you.
The hardest part for me was all the choices. Prepare to spend hours picking out faucets, toilets, sinks, stain color, siding color, shingle color, cabinets, door knobs, drawer pulls, brick color, lighting, flooring.... oh boy it's a big job. You'll find that the trunk of your car will be FULL of color swatches and tiny little samples!
In the end it's worth it though. You get the house you always wanted and everything is perfect.

Just try not to get too many gray hairs in the process.
