Think about why you're doing all this - is it purely financial or is there some other benefit? If it's financial, one trick that worked for us is putting graphs on the wall and being able to color them in (either debt reduction or savings) - it's a visual reminder of what we're working towards.
If you're also hoping to do something better with your life, then not watching TV should help you do that. Start to exercise, learn a language, go to the library. What are the things you're going to do when you're FI? Start doing them now! Basically, you need to break the habit of watching TV. For example, if you traditionally come home, eat, clean-up, and then go watch TV, try and do something else. Go for a walk/bike ride after dinner. Go work on meal planning for the rest of the month. Start prepping for tomorrow night's dinner, so you're ahead of the game and won't be tempted to eat out. Start a garden. You get the idea.
Also, it's only been a month so you haven't seen the benefits yet, only the 'sacrifice'. You need to start changing your mindset on who you want to be. "I'm a financial badass, that cooks from scratch, has time/energy to exercise......blah, blah, blah". Instead of, "I miss TV, and want my semi-status-symbol car back.....wah, wah, wah!" I'm not really making fun of you, just trying to bring in some humor here. But seriously, start changing the way you think about who you are, and your actions will be aligned closer.
