It's not an impossible schedule, you are just choosing it to be. Everyone has the same hours in the day. If a woman I know whose husband was recovering from brain surgery could take care of him, teach him how to walk and talk and rehabilitate him, raise her children, work full time, run a part-time coaching practice and lose over 100 pounds at the same time, I know you can, too, if you choose.
There are always challenges, the key is to live in the solution. The keys are going to be to find what little time you have during the week and focus on that to prepare meals that are "grab and go" throughout the week.
The other challenge is to really focus on time management and organization. The Total Health & Fitness program can help you become better at time management and life preparation.
You can succeed just by planning 15 - 30 minutes each day. It may seem impossible but let's face it, without a plan you really can't succeed.
Rest is important, but at times, it doesn't have to be the main priority. You can cut into 15 or 30 minutes of rest and create that time to manage your coming day.
The human body can do amazing things when pushed to reveal it's inner power, and this should not be a condition for the rest of your life.
