PCP Begins

So I just typed a lengthy first post ( yes I know Patrick you said just a few lines) and I managed to lose it all. Guess is an appropiate taster of many frustrations that I will be dealing with. I have been the route of gruelling training regimes and severely restrictive sports diets, but all in the context of a less punishing life schedule and with plenty of muscle-nourishing rest time. How will I manage to do the same with a very busy business schedule, little sleeping time, and the dual pressures of moving into self employment to start a risky new business from the scratch and first time parenthood looming in 6 months time?
