My struggle.

So, I did another spin class since my last post, and an Attack class (now as aggresive as that sounds it's not), it's actually a cardio class where all the moves are derived from sports.  If you go to good life you'll know what I am talking about.  Today I did a step/arobics class the followed by yoga.  Man do I ever feel good.  Today I realized something.  I go to the gym 7 days a week.  My sister always tells me that i need rest days.  I know she's right, but like I said I figured out why I can't do it.  Every other time i have done this I've always said oh I'll take a rest day here and there and here again.  Then it turned to lazy days and I quit.  I thin k I am scared that will happen again.  So I figured out what I am going do.  I am going to pick 2 days of the week and still go to the gym but just walk on the treadmill so that I don't get to feel like i am going to fail again.  If anyone else has any other ideas or thoughts, I am open to your suggestions.  Thanks abunch.
