I just got back from California and received the results of my JNCIE-M test and I passed, it was fun but it was one tough 8hr lab test. I passed it the day before my one year mark on the team which is a new record for JTAC. The record before was 1 year and 2 weeks which was set by a guy 6 or 7 years ago. It was a long year filled of many hours of study but in the end it was definitely worth it.
I'd say that the biggest part that helped me in obtaining this goal was my wife for letting me get what ever I needed for networking equipment, dropped about 5k on the lab so far, and also allowing me to spend all my sparse free time with it

It's amazing what you can do when you loved ones fully support you in it.
