I have found out you really have to love this hobby and laugh at yourself when you spend hours chasing down a problem, tools and meters all over the place , looking at the prints time and time again, then you find it a 5 second fix staring you in the face.You still have to have a sense of accomplishment with what you just figured out even though it took half the day. You have to love learning from what you did and learning how it works relay by relay . Putting the machine back together can't wait to play it after you fixed it only to have something else happen. You have to love getting the prints back out opening the machine up and doing it again. Then when you finally play your game with no problems knowing you fixed it you love it and when a problem comes up again and it will you smile get out your tools and prints and enjoy what you are doing
