I Have Bad Memory So How Do I Remeber A Different Langauge?

I have bad memory and it's hard to remeber things. I'm learning French and so far I only know 'Et' 'Vous' 'Va' and 'Ici'. Which makes the sentence fragment 'And here goes'. Everyday I recite these words to remeber them. How do I remeber a whole language with my bad memory? I also know one word in Italian which is 'omicidio' which means 'murder' because I got it off a TV Show xD.
