Where do I begin?

I am not sure what to do.  I know to diet and exercise, but where should I begin?  Should I start to strength train or just walk?  I have equipment, but I feel like I am wasting money on the equipment.  I am just afraid that I will never use that equipment.  In short, I am afraid to fail.  I want to start exercising right now but because of my fear, I am just procrastinating.  I tend to do some movement early in the morning or later at night, but should I count slow walking as exercise?  I would like to be able to move for just ten minutes without being able to worry about how much time I have left to exercise.  Where do I begin?
