Some people though, say they actually stay on track better if they weigh daily. I'm fine with that as long as they don't allow the numbers to discourage them when they don't lose.
Keep in mind there are weight fluctuations with weight that occur that may not have anything to do with real weight gain or loss. A high sodium food item like a dill pickle, popcorn, soy sauce, or even dining out (especially fast food) may make the scale go up. Then there are hormone fluctuations  which occur especially around a woman's cycle which can make the scale go up two to five pounds.  Airline travel may also cause water retention which looks like weight gain. I've even seen stress decrease weight loss efforts.
So do what you must do on the scale but pay attention to what you are eating and what happens in the context of your day to day life as well as how you personally react to scale numbers. Again, If you get discouraged easily definitely stay off the scale. You might just want to gauge your weight by your clothes and how they fit. For some this works too.
