Obstacle - Time

I do not have enough hours in the day. And what makes it worse, is that my physical unhealth, makes the hours I do have not effective. I can be busy for an hour doing physical tasks like laundry, dishes, sweeping, etc. But then I have to sit and rest, cause my body is exhausted. So how can I change the situation?

My time is divided between:

• God Time (Church activities, Bible Study activities, doing Bible study homework, etc.)
• Kid Time (Home school activities, feeding, tending, teaching, disciplining, etc.)
• Spouse Time (talking, making decisions, trying to have a date now and then, etc.)
• Household Manager Time (cooking, cleaning, organizing, picking up, running errands, etc.)
• Self Time (Blogging, Facebook, sewing, maybe reading, a bit of Relaxation)
  
• General Care Time (sleeping, eating, going to the bathroom, etc.)
• Misc. Time (driving to and fro, waiting for others, etc.)

Okay, so I already have plenty to keep me busy. And I am sure healthy people have the same or similar time obligations. So, how does a person make time for exercise?

I have heard that once a person is healthy, he/she has more energy and can be more efficient with time usage. I have been told that if health and exercise is a priority then it will replace certain areas and become a new hobby. That would be great, except I can't see where it would fit, unless I give up what relaxation I do have (but can I do that? ugh!)

So I am struggling: where can I find the time to exercise? Or am I really struggling with fear of making life changes and time is a convenient excuse?

What works for you?
