Yeah, for now you can just stare at it to read it correctly. But once you have it memorized, dont use it and please properly dispose of it.
Best way to memorize is repetition. Just repeat the phrase many times, over and over again, until you're comfortable reciting it and it just flows off your tongue. Dont worry, Allah (swt) will make it easier for you because He knows you're making an effort.
And please, if you have any other questions, feel free to ask, there are a lot of knowledgeable brothers and sisters on this Forum.
