Not everyone can train full time. My husband is an instructor and trains 2 sessions + a day, 5 days a week and also a session on Saturday. We used to do Sunday, but I think the guys who train all week really need that rest day. For us, we have been able to tackle it as a team. He's always been able to focus all of his efforts on the school and I work full time. I train 5 nights a week on top of two jobs and helping run two businesses. I think working a 9-5 and training five to six days a week is doable. Like Chris said, if you really want it. You have to be a savage to own a 10P school. Remember that.
