Working Out at Home Motivation Advice

I've recently been debating whether or not to join a gym due to my lack of motivation when working out at home. I had done some FB workouts on YouTube before and liked them so I decided to look at the workout plans here before committing to a gym. I realized that I am always more motivated when I have a plan laid out for me so I decided to give the FB Trial workout plan a try. I completed my first day yesterday and I loved it. I already feel more motivated with my workouts at home. However, my problem has always been maintaining that motivation level over longer periods of time. How do you guys stay motivated when working out at home? Do you just redo the same workout plans? Do you purchase new ones? Do you create your own workout plans? Thanks in advance for any advice you can give.
